Cast to non-builtin types

[iuliux]

A cast to a class type is turned into a constructor of that type. For example:

obj = (Cast) o;

becomes:

self.obj = Cast(o)

However, with builtin types like String, this works fine.

What do you think the behavior for translating casts should be? I realize there's a problem, but I don't see an obvious target for casts.

I think that just removing them would be better (except the built-in ones that work as they are now). So obj = (Cast) o; would become self.obj = o
Actually, I thing this would behave pretty well, or am I wrong?

I don't think we can simply drop the casts because self.x = some_string is totally different than self.x = int(some_string).

I think a reasonable approach would be:

1. perform the casts for known Java types
2. provide a configuration option for handling casts in general
3. log a warning if a cast is detected that isn't handled by the previous 2 steps

What do you think of that?

That looks good. (1. is also what I was suggesting with "except the built-in ones that work as they are now").

I'll come with a pull request shortly.
