2011-08-24 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (apply-partially):
Add an assertion to this compiler macro, requiring that the order
of the placeholders corresponding to the arguments in the
constants vector of the constructed compiled function be the same
as the order of the arguments to #'apply-partially.
tests/ChangeLog addition:
2011-08-24 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Add a test of apply partially that depends on the relative order
of its arguments.
