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
