It's a bug. The remove function is not actually defined by the library, it's a compiler special that remaps to an extern(C) function _aaDelX. As far as I can tell, it's the only one that doesn't work. All the others seem to work (e.g. a.keys).
What I would guess is happening is the compiler is trying to call remove on the AA but has skipped the part that translates to _aaDelX.
It would be good to hoist this out of the compiler and make it a UFCS call, which would also fix the problem.
