This is why I like to recommend Regexp::Common. But...
use warnings;
use Regexp::Common 'number';
$_ = '.';
/^$RE{num}{real}$/ and print "\"$_\" is a number.\n";
my $x = 1 if $_ < 5;
Outputs:
"." is a number.
"." isn't numeric in numeric lt (<) at ...
Regexp::Common considers an alone decimal point to be a number, while
the Perl compiler does not. Did you know that? ;-)
