Description danijans03 2008-01-11 04:18:55 UTC 
It is currently not possible to write something like:

enum DebugLevel { LOW, MEDIUM, HIGH };
debug(DebugLevel.HIGH)
	Logger.writeDebug("");

I think it is to restrictive to only allow Integer. An enum could easily be cast to an integer internally.

You could of course write something like:

const int DebugLevelLow = 0;
const int DebugLevelMedium = 1;
const int DebugLevelHigh = 2;
debug(DebugLevelHigh)
	Logger.writeDebug("");

But this isn't as elegant as using enums.

There is also this syntax:
debug ( Identifier )

So you can use:
debug(MEDIUM)
    Logger.writeDebug("");

To be compiled with:
-debug=MEDIUM
