We did a code review of Steve's dPrintMonth subroutine at our meeting.
I did a simple test of a question which was raised. The question was
whether \d has the special meeting of matching digits in the  of a
character class. Steve was right; \d does have the special meaning,
even in a character class.
$string = '123';
$string =~ s/[\d]/x/g;
print "$string\n"; # prints xxx
