This works

use NativeCall;

constant gid_t = uint32;
constant group = class :​: is repr('CStruct') {
  has Str $.name;
  has Str $.password;
  has gid_t $.gid;
  has CArray[Str] $.members;
};

sub getgrgid(int32) returns group is native { * }

my int32 $i = 1;
getgrgid($i);

This doesn't

use NativeCall;

constant gid_t = uint32;
constant group = class :​: is repr('CStruct') {
  has Str $.name;
  has Str $.password;
  has gid_t $.gid;
  has CArray[Str] $.members;
};

multi sub getgrgid(int32) returns group is native { * }
multi sub getgrgid(Int) { say 'Hi' }

my int32 $i = 1;
getgrgid($i);

Shouldn't it?

What does "doesn't work" mean? Please be specific about the problem and include your perl6 --version

On my HEAD build the second one fails with

Cannot invoke object with invocation handler in this context
  in sub getgrgid at test.p6 line 11
  in block <unit> at test.p6 line 15

I'm not impressed with the bug tracking. No link provided in the email, and my reply with the follow-up information got lost. Today 15.35 I wrote

Perhaps it would be an idea to include the error message​:

Cannot invoke object with invocation handler in this context

  in sub getgrgid at b line 11

  in block <unit> at b line 15

and the perl6 --version
