$.a is default(42) }; use nqp; dd nqp​::getattr(A.CREATE,A,q/$

$!a is default(42); method a() is raw { $

This doesn’t seem to be cause by BUILD, as the .CREATE part bypasses all of that.

Weird!

It does work if you add =Nil

  class A { has Int $.a is rw is default(42) = Nil };
  dd A.new.a; # 42
  $_ = A.new(​:a(34));
  .a = Nil;
  dd .a; # 42

dd A.new.a; # 42
$_ = A.new(​:a(34));
.a = Nil;
dd .a; # 42

The whole reason for me to look at this, was to prevent the explicit initialization, done by BUILDALL. If you don’t, it still doesn’t work​:

$ 6 'class A { has Int $.a is rw is default(42) = Nil }; say A.CREATE.a'
(Int)

:-(

$zis‘Nil‘withoutmyhavingtoassignanything,while‘$!z` is Any. To make `$!z` Nil I also have to assign Nil to it​:
