                    template
           Product: D

test.d:
-------------------
void funA2()(int a) {}
void funA2(char a) {} // this function get lost
alias funA = funA2;
void funA(float b) {}

static assert(__traits(getOverloads, test, "funA", true).length == 3);
-------------------

Result:
Error: static assert:  `2LU == 3LU` is false


Note: stable shows "`0LU == 3LU` is false" due to issue 20821
