Have often wanted a way to tell whether a scalar was a number, and rolling a regex each time seemed wasteful given that Perl knew what it was anyway. So a user-friendly way to get at the SvIOK and SvNOK results would be great. The pedestrian way would be a builtin: isnum() or similar. But we have enough creativity here I'm sure we can come up with something far more obfusc^Wconcise :-) -- Peter Scott Pacific Systems Design Technologies
