AssociativeArray.opIndex

[H. S. Teoh]

In attempting to fix issue 5030, I'm finding that defining
AssociativeArray.opIndex gives an odd error when druntime is compiled:

dmd: mtype.c:4411: StructDeclaration* TypeAArray::getImpl(): Assertion `impl' failed.

This error only happens when opIndex is declared like this:

	Value opIndex(Key key, int file=__FILE__, int line=__LINE__)

It seems to be OK when declared without the extra parameters, but then
if there's any error in the function body, such as a missing return
value, another strange error happens:

	src/core/thread.d(2835): Error: undefined identifier module thread.keys

Even though the error has nothing to do with thread.d at all.
Apparently there are some unstated assumptions about what's in struct
AssociativeArray?
