Range + detached method + map with &sub = "Cannot find method 'count' on object of type NQPMu"

Migrated from rt.perl.org#131623 (status was 'resolved')

Searchable as RT131623$

From @zoffixznet

A WhateverCode detached map or a &sub undetached map works fine​:
  m​: ^2 .map​: *.say
  rakudo-moar 86e7b2​: OUTPUT​: «0␤1␤»
  m​: (^2).map​: &say
  rakudo-moar 86e7b2​: OUTPUT​: «0␤1␤»

But explodes if you try to both detache and use the &sub map​:
  m​: ^2 .map​: &say
  rakudo-moar 86e7b2​: OUTPUT​: «===SORRY!===␤Cannot find method 'count' on object of type NQPMu␤»
