Remember, we both found, independently, that combining separate files
yields from a 10-30% performance increase. I have only talked to 2
On synthetic benchmarks. On real apps, which do databases, calculations, network, etc. that would be probably no more than 5%, probably even less. And I don't see any application shipping in this format.
This is a very problematic issue - adding a feature into a language that serves only very specific very narrow performance scenario but which will inevitably be widely abused in cases which have nothing to do with that scenario.
the feature unnecessary. If you'd like, I could put you in contact with
developers who have been struggling with combining files for several
years now.
Why were they "struggling" - only problem existing with it is namespaces, and they certainly couldn't try to use namespaces for years? If they had other problems, they will keep having them and multiple namespaces per file are not going to help them.
Anecdotally, I heard of a recent file-combining optimization to a very
popular CMS that resulted in a 45% performance improvement. Improving
Did they use bytecode caching?
Anyway, I have hard time believing PHP include is so broken, but if it is - it should be fixed, not through creating syntax-level workarounds but directly.
really the only reason not to implement the multiple namespaces per-file
I think I described my reasons now multiple times.
