Hi!

I want to request a C/C++ feature that i think is good.

MACRO

You know that you could write:
<?php
#define PF private function
#define SCOPE_CLASS(x) class MyProject_ ## x

class UseMacro
{
PF preSave($object)
{
//...
}

}

SCOPE_CLASS(Internal)
{

}

And then run it through CPP (gcc -Mcpp -E - - < in.php > out.php) and
get all the macros processed?

Although I am a C developer and use macros I think it'd be horrible to add them to PHP (+ it's been discussed and rejected many times in the past).

Macros make it very hard for a third party person to read your code + goes directly against the verbosity spirit we've always had in the PHP project. Forget also the fact that it creates a lot of problems with solutions such as debuggers.

I suggest if it's something you really feel you need then implement it externally to PHP as part of your build and deployment environment. There are a variety of templating/pre-processor solutions out there including the C-compiler tools themselves.

This has been brought up countless times and has always been rejected
(browse the archives if you aren't convinced).

Anyhow, I just hope I never have to maintain code you write in this fashion.
Pre-compilation macros are very out of character in the dynamic languages
paradigm and I doubt they'd be useful in any case. The examples you gave
convinced me once and for all that this is a very² bad idea. There's a
reason why no modern language uses three letters tokens for common
statements, I'll let you guess what it is.

Anyhow, merry Christmas.

P.S.: SCOPE_CLASS ? Have you ever heard of namespaces ?

FWIW, you could use Prep ( https://github.com/andreiz/prep ) and GPP ( http://en.nothingisreal.com/wiki/GPP ) to accomplish this.
