txt: ## p5.md
  class X::Syntax::P5
  
  Compilation error due to use of Perl-only syntax
  
  ```raku
  class X::Syntax::P5 does X::Syntax { }
  ```
  
  Syntax error thrown when some piece of code is clearly Perl, not Raku.
  
  For example
  
  ```raku
  for my $a (1, 2) { };
  
  ```
  
  dies with
  
  ｢text｣ without highlighting
  
  ```
  
  
  ```
  
  ===SORRY!===
  This appears to be Perl code
  
  
  ```
  
  
  ```
