I'm not sure I understand this. Do you then import a and b into another
module to reproduce the error? This doesn't do it for me...
Anyway, I was wrong calling this a Phobos bug. It's clearly a DMD bug,
since the error message
static assert (is(Tuple!(string,float) == Tuple!(string,float)))
is false
is completely meaningless.
