Subject: guile: ",option prompt VALUE" only accepts literals
Date: Tue, 04 Dec 2012 11:29:08 +0800

Package: guile
Version: 2.0.7
Severity: minor

Dear maintainer

The REPL prompt option accepts #f, strings, thunks, and procedures of
one argument.  However, only the first two can be set using the
meta-command ,option; one must use repl-option-set! for thunks and
procedures.

It seems that VALUE is not evaluated.
