The problem is that Lazarus is based on Free Pascal, which may have
problem wrapping C++ code which is what Oleg wanted originally.

"Fight"?

Why is it a stupid idea? I recall re-implementing a small Perl program
(which ran too slowly) in Vala, and it performed much better, so I was
happy. I have not done any GUI programming in Vala, but translating
something to C is a valid approach.

Are you implying that Vala is not a "real" programming language?
