Declarations of constants

[Ingo Blechschmidt]

Hi,

  # Way 1
  my $MEANING_OF_LIFE is constant = 42;


  # Way 2
  my &MEANING_OF_LIVE = -> () { 42 };
  # or
  sub MEANING_OF_LIVE () { 42 }

  # Then one can use sigilless constants:
  say MEANING_OF_LIVE;


  # Way 3 (still possible?)
  use constant MEANING_OF_LIVE => 42;


  # Way 4 (evil?)
  macro MEANING_OF_LIVE { "42" }


  # Way 5 (overloading of the numification of Class -- evil)
  Class does role {
    method *prefix:<+> (MEANING_OF_LIVE $class:) {
      42;
    }
  }
  class MEANING_OF_LIVE {}
  
  say +MEANING_OF_LIVE;


  # Please add more ways :)
