I have code like this in dcollections:

HashMap remove(K key, out bool wasRemoved) {
cursor it = elemAt(key);
if(wasRemoved = !it.empty)
{
remove(it);
}
return this;
}
However, this does not compile with the following message:
dcollections/HashMap.d(561): Error: '=' does not give a boolean result
line 561 is the if statement.
Since when did bool = bool not give a bool result?
Don't you mean bool == bool, not bool = bool?
No. I meant bool = bool. I'm not comparing two bools, I'm assigning to a
bool, and then using if on the result. At best, this is a bogus error
message.
