Absolutely. Thanks for the report!

Turns out this is a problem with the assumptions behind compiler macros and
source transforms: when the source doesn't contain the keyword argument
keywords, you'd expect the expansion to mismatch the arguments list, not
apply the transform and go on. However, due to a thinko instead of going on,
ABCL throws an argument-list mismatch error.

Committed a fix just a minute ago; compilation of FOO now works. Please
verify that your issue has been solved and confirm!

Bye,


Erik.
