[Discussion] Dots and spaces in GPC variable names

Hi all, With parse_str() usage without a second parameter being deprecated, I was looking to possibly drop the behavior where it replaces spaces and dots with underscores in the result array, and ... As it often turns out - it's not that simple, because it re-uses the code that handles GPC vars. I didn't even know this mangling happened with GPC vars. I can only assume that's legacy from the the register_global days, as I certainly don't see a reason for it now. Am I missing something? And more importantly, can we change that? It's a significant BC break, yes, but the current behavior is horribly broken IMO. Cheers, Andrey.
