Function overload error: Function error filtering in Receiver Type #964

Open supemeko opened 4 years ago

supemeko commented 4 years ago 
class A
    function func(int i)
        print("func_int...")

    function func(string s)
        print("func_string...")

class B extends A
    function func()
        print("func_noarg")

    function func(bool b)
        print("func_boolean...")

init
    let b = new B()
    b.func()
    b.func(true)
    b.func(1) //Too many arguments: 1 given, but only 0 expected.
    b.func("1") //Too many arguments: 1 given, but only 0 expected.

when a class extends another class and this class own a function as the same name as super class , this class will lose other same name function of super class.

class A
    function func(int i)
        print("func_int...")

class B extends A
    function func()
        print("func_noarg")

init
    let b = new B()
    b.func()
    b.func(1) //Too many arguments: 1 given, but only 0 expected.

Maybe I can add conditions to fix it QQ截图20200806113017

supemeko commented 4 years ago

When I tried to fix it, cause exception

You encountered a bug in the interpreter: java.lang.Error: wrong number of parameters when calling func B_func(B546_1, 1) at supemeko line 10

Stack trace: at : supemeko, line 10 ... when calling init_test() in supemeko:1 ... when calling main()
