One thing is the length of the name of a Perl variable (how many characters in that name). I've worked with languages with limits like 5 or 6 chars or stuff like you "can use 32 chars, but only first 8 are available to the linker". As far as I know, the number of characters in a Perl $var name is so huge that in a practical sense it won't be reached.

How many bytes can be assigned to a $var is a different thing. As ikegami points out. But then again we get to the practical matter of how many chars(bytes) make sense to assign to a single Perl variable? I would argue that once this gets past a couple of billion (or even just a 100 million), the algorithm is suspect.
