Please tell me that's a bug?
Not a bug. From spec:
http://dlang.org/expression.html#AssignExpression
Assignment operator expressions, such as:
a op= b
are semantically equivalent to:
a = cast(typeof(a))(a op b)
Seems questionable to me. Anyone know the rationale? If a = b;
is disallowed, I don't see why a += b; should be more
acceptable.
Questionable or not, this is the C behaviour we might not depart
from.
