You'll want to use static_scalar_expr when applied with my patch.

In tune with the current 'const' patches by Sterling, and because I found
it useful (and more consistent than the original behaviour IMHO), attached
is a patch which implements compile-time constants in the global scope:

<?php

const something = 2, something_else = 4;

?>

The behaviour is the same as `define()`, only implemented in the compiler
instead of as a function.

I've been thinking about this for awhile, and seeing these patches about
'const' at compile-time I thought I would throw this in here now...

Instead of patching the engine for these constant values, wouldn't these
things be better served in a module? I've already worked on a basic
module that hooks into zend_compile() and does pre-processing before
giving the script over to PHP... Hence you'd have something identical to
C's preprocessing.

<?php

#define MYVAR 1;

Echo MYVAR;

?>

If there is interest, I'd like to be able to include this module in PHP5
once its been cleaned up...

John
