So, if change the fun to static, it cannot pickup the pointer and therefore can't call anything of the aliased object. If I get it right...

I think so. But this is a guess, as the generated call clearly never uses that 'this' member. Interesting to me that it calls that member 'this', when 'this' is already defined!

Hmm... yes, I see...

cool option, by the way... didn't know anything about it. What does -ast do?

-vcg-ast means take the generated AST before optimization (I think), and output a d-source-like file (called file.d.cg) that shows the representation. Super useful when you are trying to figure out what the compiler does to your code. It only happens if compilation succeeds.

-ast, I don't think does anything, but not sure if that's what your question was.

The reason you don't know anything about it is because it's a debugging option and not documented :) At least, that's what I was told...


If you click on the AST button on run.dlang.io, you get the same thing.

Thanks a lot.
