You can't use the paste operator (#) there because c2x is a defvar. Defvars and undefined identifiers are taken literally by paste, due to its frequent use in forming record and class names.

This behavior is noted in the Programmer's Reference, but I think I will add a more prominent note. I wonder if we should change the behavior so defvars are treated normally.
