Interesting. Using Perl 5.8.8 rather than 5.10 makes the same saving for 'Big hash':

Big hash: 61 Mb
More hashes: 52 Mb
Savings: 16%

so should we all use 5.8.8 rather than 5.10? Actually 14 (or 16) % is sufficiently small to be irrelevant for most purposes. Clarity of code is the more important factor (not that I'm claiming that my code is any clearer mind you), especially for a first cut - optimize later if you need to.

Perl reduces RSI - it saves typing
