The specification says:
The expression: a op= b
is rewritten as: a.opOpAssign!("op")(b)
A similar statement is made about opIndexOpAssign. However, what actually
happens is that the template parameter is set to "op=", as this program shows:
struct S
{
void opIndexOpAssign(string op)(int x, int i)
{
pragma (msg, op);
}
void opOpAssign(string op)(int x)
{
pragma(msg, op);
}
}
void main()
{
S s;
s[1] += 2;
s += 3;
}
This prints the following on compilation:
+=
+=
