nnmail-split-fancy

[Sebastian Luque <spluque@gmail.com>]

Hello,

Can somebody please clarify why using concat to provide a regexp in the
following nnmail-split-fancy is not allowed?  For example:

(setq nnmail-split-fancy
      '(| ("from" (concat "my " "regexp") "MyGroup")
	  (: spam-split)
	  "mail.misc"))

does not work, and would send all messages to the bogus group, but without
using concat:

(setq nnmail-split-fancy
      '(| ("from" "my regexp" "MyGroup")
	  (: spam-split)
	  "mail.misc"))

is fine.  The reason I want to use concat is to simplify maintenance of
the regexps in several lines.

Thanks in advance,
