Re: [Vala] Interfacing various languages

[Luca Bruno <lethalman88 gmail com>]

There's no need for a plan to make the compiler more generic. Anyway,
there's a c++ branch in vala created by me, and I had hard time mapping
vala to c++ for two reasons:
1) Classes can be used as structs, even Qt does that fir Lists for example.
2) Templates cannot be easily mapped from vala generics to c++ templates,
unless you specialize the class. E.g. List<T> to List<string> and call that
StringList in vala.

The second point can be reworked to make vala a complete rewrite of c++
somehow, but wasn't my intention in the branch. However the fist point is a
real problem.

If any of you has a project that maps vala to another language, and you
feel the need for a more generic interface of a particular component of
vala, I'm willing to help with that.
