we already have declare() for this purpose exactly. http://docs.php.net/declare

Alexey, perhaps ... and mindfart following.

Looks like you misread Alexey's post. He was talking about declare construct, not define() function. Apologies to you Alexey, as the point that you made was very relevant, and my reply was a response to a misreading as Felipe as kindly pointed out.

Yes, extending declare would be a more elegant approach, but there is a problem with an extended the declare syntax -- statements such as: declare( allow_override_builtins = 1); would generate additional compiler warnings when used on all previous versions, and one of my aims was to enable B/C back to PHP 5.3 at least. Also as declare is a pure compiler construct that only applies to the source, there would be no equivalent mechanism for, say, defining a namespace-wide set of pragmas without further modifying every source file.
