  m​: class Foo is Int {}; my Foo $x .= new​: 42; say $x; say $x.WHAT;
  rakudo-moar bb4579​: OUTPUT​: «Type check failed in assignment to $x; expected Foo but got Int (42)␤ in block <unit> at <tmp> line 1␤␤»

This was broken by the fix to make it correctly handle >64bit ints, but apparently there are even articles that show how to subclass Ints​: https://irclog.perlgeek.de/perl6/2017-09-19#i_15187511

The likely fix would be Int.new changed to this​:

  method new (Int() \value) {
  nqp​::p6bindattrinvres(self.bless, Int, q|$!value|, nqp​::getattr(nqp​::decont(value), Int, q|$!value|))
  }

But that currently segfaults​: https://rt-archive.perl.org/perl6/Ticket/Display.html?id=132126

In that case, resolving the ticket.

The RT System itself - Status changed from 'new' to 'open'

@skids - Status changed from 'open' to 'resolved'
