Re: [Vala] Properties == GObject properties?

[Luca Bruno <lethalman88 gmail com>]

We don't put much interest on reporting C naming conflicts to the user.
That's not good, however the compiler needs many (but not major) changes to
achieve this, and there are other priorities: in the sense that now you're
stressing the compiler, but in normal usage you don't.
Also, we don't want to mangle the name in case there's a conflict at the C
level, because you can't otherwise reason on the name you expect: let's say
that void @if() { } was renamed in C as _vala_if() { }, I bet that's not
what you want (other than the fact that you don't want to call a method @if
in general).
