Constants aren't supported #28

Closed hikari-no-yume closed 9 years ago

Currently there's no way to reference them, because bare names are variables. You could add a prefix to mean a constant like Snowscript does, which has !FOO_BAR translate to PHP FOO_BAR.

But here's a more radical and perhaps nicer idea: Why not just make entirely uppercase names be constants? So if I want to check against INF, I could do if foo != INF. The main downside here is it might not be obvious if you didn't know the rule, and it'd stop you from dealing with projects that use $UPPERCASE_GLOBALS - but those projects probably suck.

This does also raise a problem of how to declare them. You could make FOO = 3 implicitly be a constant declaration, or you could have const FOO = 3 like PHP. I'm not sure which is nicer.

Implemented in 7fe4431 using all uppercase syntax, as it's much nicer.

If legacy support is needed it's possible to use PHP's constant function: constant('myLowerCaseConstant').
