Esteemed Monks -

Here is my humble question for the day: Perl permits to access variables whose names were created in some (possibly systematic) way in the way illustrated in the following example.

Example:
perl -le '$a1 = 3; $a2 = 4; $c = 2; print ${a . $c}'

[download]
returns the correct output '4'.

So here's my question: How can I obtain the list of all variables whose name matches a certain pattern? I am thinking of something analogous to globbing ('$a*') over variable names. Ideally, I would like to write code like 
for ( @a )
{
   print ${ $_ };
}

[download]
where @a should hold the names of all variables starting with $a, say, or mathing some other pattern of the variable name (not content!).

Did I explain this comprehensibly? And, if so, any help on this?

Cheers -

Pat
