With an empty list, mapn cannot know the number of values proc would
return. mapn therefore needs to know the arity of proc. To provide for
existing callers of mapn, we add a map2 function variant. Finally, we
add a test case testing mapn on an empty list.

* ccwl/ccwl.scm (collect-steps): Deduplicate global workflow input
keys across branches of tees.
* tests/ccwl.scm (key, collect-steps): New variables.
("rename should work even on the final output of a
workflow"): Update order of elements in expected list.
("tee must deduplicate global workflow input keys"): New test.
* ccwl/utils.scm (append-mapn): Delete function.

number of elements.

plist->alist is not used anywhere. pairify is quite sufficient to take
on its functionality.
* ccwl/utils.scm (plist->alist): Delete function.
* tests/utils.scm ("plist->alist"): Delete test.

* ccwl/utils.scm (syntax-lambda**): Document default default value.

argument should be #f", "default default value of syntax-lambda**
n-ary argument should be the empty list"): New tests.

* ccwl/utils.scm (lambda**): Change "default value" to "default
default value" in docstring.

list"): Change "default value" to "default default value".

This is a purely cosmetic change just to keep definitions outside the
test cases.
* tests/utils.scm (plist-ref): Move ahead of test-begin.

* ccwl/conditions.scm (&unrecognized-keyword-assertion,
&invalid-keyword-arity-assertion,
&invalid-positional-arguments-arity-assertion): New conditions.

and (ccwl conditions).
(group-keyword-arguments): Raise &invalid-keyword-arity-assertion on
error.

&invalid-keyword-arity-assertion and

srfi-1) and (ccwl conditions).
("lambda** should raise an &unrecognized-keyword-assertion on
unrecognized keywords in arguments with syntax objects as irritants"):
Check for &unrecognized-keyword-assertion.
("Unrecognized keyword argument passed to lambda** should raise an
&unrecognized-keyword-assertion condition", "Unary lambda** keyword
argument passed multiple arguments should raise an

@@ is shorter and looks neater with fewer quotes.
* tests/ccwl.scm ("stdin input should not have inputBinding"),
tests/utils.scm ("unsyntax-keywords"): Use @@ instead of module-ref
and resolve-module.

* ccwl/utils.scm (lambda**): Support #:allow-other-keys. Update
docstring.
(syntax-lambda**): Update docstring.
* tests/utils.scm ("Allow other keys in lambda**", "Allow other keys
in syntax-lambda**"): New tests.
|
|
* ccwl/utils.scm (lambda**): Error out on invalid keywords (that is,
keywords other than #:key, #:key* and #:allow-other-keys).
* tests/utils.scm ("lambda** should error out on unrecognized keywords
in arguments"): New test.

* tests/utils.scm: Remove stray syntax-lambda** form.

I have tripped up several times on the differences between lambda**
and syntax-lambda**. No longer! Making syntax-lambda** as close as
possible to lambda** makes the code much more readable and align
better with common sense.
* ccwl/utils.scm (syntax-lambda**): Do not ignore the first
identifier. Accept multiple values as arguments, not a single syntax
object.
* ccwl/ccwl.scm (command): Update use of syntax-lambda**.
* tests/utils.scm ("syntax-lambda**", "syntax-lambda** with default
values"): Update tests.
|

* ccwl/utils.scm (lambda**): Set default value of lambda** n-ary
arguments to the empty list. Document this in the docstring.
* tests/utils.scm ("default value of lambda** unary argument should be
#f", "default value of lambda** n-ary argument should be the empty
list"): New tests.
|
|
* ccwl/utils.scm (syntax-lambda**): Add example to docstring
documenting support for default arguments.
* tests/utils.scm ("syntax-lambda** with default values"): New test.

* ccwl/utils.scm (lambda**): Support default values for arguments,
both unary and n-ary.
