[Vala] enums

[pancake <pancake youterm com>]

I have been doing some bindings for Vala and noticed something inconsistent in the naming of enums.

 // VALID
enum Foo {
   1FOO
}

// INVALID
enum Bar {
   33
}

The thing is that you can name an enum like Foo.1FOO, but not Bar.33, if the reason to support enums prefixed 
with a number is because the C translation doesnt breaks anything.. why do using numeric values breaks?

Is this defined by the Vala language or it’s just a bug?
