Is there a way to find out how much memory the GC used currently?

Does not seem to be possible. Would have been nice.

There is an "unofficial" function gc_stats here: https://github.com/D-Programming-Language/druntime/blob/master/src/gc/proxy.d#L276

And how can I use it? import gc.proxy; doesn't work.

You need to add <dmd-install-path>/src/druntime/src to the import search paths.

Or simply declare the extern (C) function in your code.

And what is with the return type? It's a struct. You must import it.

You don't have to import it.  The layout of the struct isn't going to change any time soon.  Just copy/paste the definition into your code.  Or import it if you want.  It's just that the original definition of this stuff is in a portion of Druntime that was never intended to be published to a location where the module could be imported by users.
