I'm new to Perl, but am enthusiastically writing a Perl program that converts a simpler scripting language into valid Perl syntax. One of the constructs of this simple language is: MyVar IsNumber - a true bool if MyVar turns out to be a number. I've created a simple regex to test for numbers: 
my $IsNumber = '/^\d+$/';

[download]
The right-hand part of the expression is stored in a variable I call $rValue. 
$rValue = "$IsNumber";

[download]
Now I want to convert the right-hand IsNumber variable into the actual regex. I have no idea how to do this - and no idea even what to look for in the documentation. Intuition has me trying things like this (none of which work). 
$rValue = $$rValue
$rValue = `eval $rValue`

[download]
Again, I want the resulting value of $rValue to be '/^\d+$/' Any help would be fantastic.
