We could get into trouble here. Imagine:
static $a = -'12.8';

This should be -12.8, but what if locale changes and . is no longer 
decimal separator? Moreover, what if locale changes between compile and 
runtime? We get entirely different code now.

I think it's not the feature that can be "tossed in quickly" - it can 
have some obscure side effects, as I described in my later emails.
