It seems to be a recursive mixin. Every time it's instantiated, it
gets 4 bytes bigger.
Seems to be triggered by opOpAssign; maybe it's the change to
opOpAssign in this release: "+=" was passed to opOpAssign
now it's "+". There's code in opOpAssign which is clearly wrong - it's
stripping off the "=", which no longer exists.

If you don't think you can fix this really quickly, I think we should
remove it completely from this release, and wait until the next one.
It doesn't seem urgent to me, but getting a release out is urgent.
