Re^2: Speed up hash initialization loop

bulk88:

So the compiler doesn't do a 'common subexpression elimiation' optimization? Or does it do such a thing, but it can't optimize that due to the possibility of too much "magic" going on?

Correct. $profEvntVar may be magical and return a different hash every time its read. In that hash, slice {$customProf} might be magical and different every time. If you write the var X many times in source, it will be called/read X many times in source. There is no caching.	[reply]

I'm not using a compiler... actually I didn't even know there where perl compilers, but if you point me in the right direction I'd be happy to learn	[reply]
