Sure U can :-) I use this type of construct all the time, even with strict

Having said that, I would also say that $a and $b were a bad choice for
the sorting vrbls. Let's hope something more intuitive (special looking)
for Perl 6 - like a separate namespace/syntax for special vrbls (like
maybe $^a, $^b or some such).

Is there a reason you don't write it
my ($characterString, $numberString) = $string =~ /^([^\d]+)(.*)$/o;
This will assure the values are not defined if the regex fails. I also
added o.

I have a string, $a for arguments sake, that contains a

Ah, you made me go back and reread the manual on this. It does sound like
it doesn't matter if there's no variable to interpolate. Although- when I
recently did some timing, it seemed to make a very slight difference.

Maybe you're used to some old behavior in Perl, but that doesn't
appear to be the case in 5.8.8 at least. I get this output:

Ah. Okay, I see why that worked now. $1, $2 et al are scoped to the
current block, so in this case you are right. If you were to do

How about something like this?
#Check the length
unless(length($myScalar) != 8){
die(Bad Scalar! Bad!\n);
}
#Get the parts
if($myScalar =~ /^([^0-9]*)(\d+.*)$/ ){
print $1 $2\n;
}
NOTE: NEVER name your variable $a. $a
