In C++-land, I consider them a useful alternative to integer macro constants, so long as you have the ability to manually specify the 'backing' type. (like you can do with some MSVC language extensions and as a part of the new C++11 standard) This has the advantage that you fundamentally can't do weird things like &MAX_ARRAY_SIZE, etc. but this isn't actually an issue in Angelscript.
Actually, strongly-typed enums could be an interesting feature in of themseves.
