Anyway, I don't think adding necessary checks for such things, and slowing define() down (even if it's negligible) is warranted in such cases.

Hi Jochem,
you can get the valu of that constant with the constant() function and use such a constant with defined() so forbidding this would at least be a BC break. btw. the same goes for reserved words so define('echo', 42); is valid too but "echo echo;" doesn't work :-)
