Maybe we will do that in the future. For now I'm quite happy with a
single drop-in file instead of a whole bunch of scripts (though I think
it boils down to three really needed ones?)
However I just changed how the mb_string checking. It now only happens
once and sets a define. Don't know if the speed enhancements are
impressive but they are a small step:
before:
27 calls to function_exists -> 0.0002715s
14 calls to defined -> 0.0000597s
after:
1 call to function_exists -> 0.0000030s
2 calls to defined -> 0.000000?s
