Hi Ilija,

Just to make sure I'm not misunderstanding something here - Symphony and =
Laravel (or anyone else) can get the exact same performance benefit =
you're talking about, if they use either a leafing `\` or `use =
function...` in their own code, today, correct?


I'm not going to pretend to know how many files either project has that =
uses global functions, but neither of those two existing options seems =
particularly "hard to come by" in my mind.


Cheers
