Method name conflicts with another definition.

Note

Methods declared with the syntax fn f(self : T, ..) will be promoted to regular function in the future, declare the method using fn T::f(..) to avoid name clash.

Erroneous example

type A Int

fn f() -> Int {
  3
}

fn f(self : A) -> Int {
  self._
}

fn main {
  println(f())
  println(A(3).f())
}

Suggestion

You can defined the method as A::f:

fn T::f(self : A) -> Int {
  self._
}

However, defining a method with T:: prefix makes it impossible to be invoked as regular function. If you wish to call the method as regular function, then you have to rename either the method name, or the regular function name to resolve the name clash.

fn f_(self : A) -> Int {
  self._
}

fn main {
  println(f_(A(3)))
}
