Require non-absolute trait method references to be unambiguous

Hi internals, Currently, when writing something like use T1, T2 { func as renamedFunc; } where both T1::func() and T2::func() exist, we silently allow this and just assume that it is referring to T1::func(). See https://3v4l.org/6h3PM for a more complete example. I would like to make this an error in PHP 8: > Fatal error: An alias was defined for method func(), which exists in both T1 and T2. Use T1::func or T2::func to resolve the ambiguity in %s As the error message indicates, the ambiguity is resolved by writing use T1, T2 { T1::func as renamedFunc; // or T2::func as renamedFunc; } depending on which of those you actually meant. This is implemented in https://github.com/php/php-src/pull/5232. Does anyone see an issue with making this change? Regards, Nikita
