Example Vala progam using keywords

In Vala you can name variables using C keywords and this is allowed in Vala but not when the generated C code is compiled, e.g.

$ valac keywords.vala

Comment 1 Robert Ancell 2013-01-08 00:41:39 UTC 
Ideally you would be able to use these keywords and they would be mangled when converting to C. If not, I would expect the compiler to not allow them to be used.
