cl-macroexpand

cl-macroexpand is an alias for `macroexpand' in `cl.el'.

(cl-macroexpand FORM &optional ENVIRONMENT)

This function is obsolete since 24.3;
use `macroexpand' instead.

Return result of expanding macros at top level of FORM.
If FORM is not a macro call, it is returned unchanged.
Otherwise, the macro is expanded and the expansion is considered
in place of FORM. When a non-macro-call results, it is returned.

The second optional arg ENVIRONMENT specifies an environment of macro
definitions to shadow the loaded ones for use in file byte-compilation.
