J> I' trying to select correct variable at compile timeusing the J> defmacro, but it seems that I don't understand how to use it inside J> let definitions. Here is the problem: J> (defmacro my-load-user-init-file () J> (cond J> ((boundp 'load-user-init-file-p) J> (intern "load-user-init-file-p")) J> ((boundp 'init-file-user) J> (intern "init-file-user")) J> (t J> (intern "dummy")))) J> (defun test () J> (let* (((my-load-user-init-file) t) J> ) J> 'ok)) There's no evaluation, and hence no macro expansion, happening in the place where the let-bound symbol is expected. let is a _special_ form.

(require 'cl) (defun test () (letf (((my-load-user-init-file) t) ) 'ok)) `letf' is merely a macro.
