Chapel: Overriding methods with variadic arguments

[e-kayrakli]

Summary of Problem

Overrides of methods with variadic arguments are never called. Parent's method is invoked, instead.

Steps to Reproduce

Source Code:

class Parent {
  proc foo(elts: int ... ?nElts) {
    writeln("Parent");
    for e in elts do writeln(e);
  }
}

class Child: Parent {
  proc foo(elts: int ... ?nElts) {
    writeln("Child");
    for e in elts do writeln(e);
  }
}

var p: Parent;
p = new Child();
p.foo(1); // prints out "Parent"

Compile command:

chpl foo.chpl

Execution command:

./foo

Associated Future Test(s):
Not yet.

Configuration Information

• Output of chpl --version:

chpl Version 1.15.0.5260a416af

Thanks for reporting!

@mppf and I agree this is a gating issue due to blocking #7768 and #8488, with no great work-arounds available.

Thanks, everybody.

In fact, I realized that the problem is really the overriding variadic methods. It is making things difficult to abstract.
If possible, add this in to do list. I really appreciate.
