Regexp::Common considers an alone decimal point to be a number,
while the Perl compiler does not. Did you know that? ;-)
Hrm, that's unfortunate :-/
Well, I'll still take this as an argument in favor of using modules
like Regexp::Common.
Why am I not surprised...
<argument previously stated in this thread snipped>
BTW, I've posted the following to RT:
[cpan #6940] lone . (decimal) considered a match for $RE{num}{real}
-------------------------------------------------------------------------
perl -MRegexp::Common=number -e 'print "oops\n" if "." =~
/$RE{num}{real}/'
