  # NAME
  
  Rakudo::Version - provide a "rakudo version" pragma
  
  # SYNOPSIS
  
  ```
  # Exactly this version
  use rakudo v2022.01;
  
  # From this version onward
  use rakudo v2023.02+;
  
  # More elaborate checks with a Callable
  use rakudo { $_ ~~ v2022.01 || $_ ~~ v2022.07+ }
  
  # Custom error message
  use rakudo {
      $_ ~~ v2022.07+ || die "$_ is not recent enough for this"
  }
  
  ```
  
  # DESCRIPTION
  
  The Rakudo::Version distribution provides a `use rakudo` pragma that allows one to specify with which version of Rakudo a program is supposed to run.
  
  Version checking occurs either by specifying a `Version` value (which will be smart-matched with the current compiler `Version`), or it can be a `Callable` which will be given the current `Version` value, and which should return a `Bool` indicating whether or not the Rakudo release is acceptable.
  
  # PRIOR ART
  
  The [RakudoPrereq](https://raku.land/zef:raku-community-modules/RakudoPrereq) module, originally by `Zoffix Znet`, provides a more general approach to the problem of limiting a program to a specific release.
