我AT-POS为类定义了方法并导出了[]运算符.[]但是,当我在该类的实例上使用时,编译器忽略了我定义的运算符.

这是代码:

unit module somelib;

class SomeClass is export {
    method AT-POS(@indices) {
        say "indices are {@indices.perl}"
    }
}

multi postcircumfix:<[ ]> (SomeClass:D $inst, *@indices) is export {
    $inst.AT-POS(@indices)
}

#! /usr/bin/env perl6

use v6.c
use lib ".";
use somelib;

my $inst = SomeClass.new;

$inst[3, 'hi'];

# expected output:
#   indices are 3, 'hi'

# actual output:
#   Type check failed in binding to parameter '@indices';
#   expected Positional but got Int (3)
# …
