i agree. =20

here is a scenario:

i was wrote an extension, and i need to call some PHP function like =E2=80=
=9Cstrtr (http://lxr.php.net/s=3Fdefs=3Dstrtr&project=3DPHP=5F5=5F4)=E2=80=
=9D  =E2=80=9C*trim=22  or a function in =20
another extension but it doesn=E2=80=99t have a common C function. Howeve=
r, i don=E2=80=99t want to copy the implement
code into my extension.

so, i have two options:

1. copy the duplicate code into my extension, It can be fast in this way,=
 but the code is not beautiful.
2. call call=5Fuser=5Ffunction(=5Fex) , it=E2=80=99s slower than the firs=
t option, but the code is more simple and beautiful than the first option=
.


cheers,
Wei Dai
