Hi; commit 6fc4d0124d633d1b3ddc5af82967f23bd17556f8 Author: Andy Wingo Date: Thu Sep 3 12:19:39 2009 +0200 That commit removed $expt completely without even adding a deprecated alias (like commit ad79736c68a803a59814fbfc0cb4b092c2b4cddf did for the other $foo functions). This removal caused a bug in aisleriot [https://bugzilla.gnome.org/show_bug.cgi?id=649730] which was quite hard to track down without a deprecation warning; so the attached patch adds a deprecated alias that does warn.
