Yes, regex... But would that be considered true interpolation?
The idea of searching within word boudaries for a string starting with \$ occured to me several times, but I have always thought of it as not being very practical. Let me put it this way (this time with math):
$n = 1;
$m = $n*2;
$o = $m*2;
$s = "$n $m $o\n";
print $s;
$n = 2;
print $s;
^d
1 2 4
2 4 8
Sure this is a simplistic example (as was my previous), but what when you have 1000+ more lines of code, wouldn't it be alot easier to control? Is the only way out to run a regex after assignment? There must be another way... Think of the possibilities!
Am I suffering from fuzzy-logic syndrome?
