Not at present. I think it would be fairly easy to add such a feature,
because it just has to remember whether any non-fixed quantifiers were
encountered while compiling. But would this be useful? A pattern such as
A|BC|DEF would come out as "matches fixed-length strings", but they are
not all the same length.
