  # NAME
  
  Raku port of Perl's lcfirst() / ucfirst() built-ins
  
  # SYNOPSIS
  
  ```
  use P5lcfirst;
  
  say lcfirst "FOOBAR"; # fOOBAR
  with "ZIPPO" {
      say lcfirst;  # zIPPO
  }
  
  say ucfirst "foobar"; # Foobar
  with "zippo" {
      say ucfirst;  # Zippo
  }
  
  ```
  
  # DESCRIPTION
  
  This module tries to mimic the behaviour of Perl's `lcfirst` and `ucfirst` built-ins as closely as possible in the Raku Programming Language.
  
  # ORIGINAL PERL 5 DOCUMENTATION
  
  ```
  lcfirst EXPR
  lcfirst Returns the value of EXPR with the first character lowercased.
          This is the internal function implementing the "\l" escape in
          double-quoted strings.
  
          If EXPR is omitted, uses $_.
  
          This function behaves the same way under various pragmata, such as
          in a locale, as "lc" does.
  
  ucfirst EXPR
  ucfirst Returns the value of EXPR with the first character in uppercase
          (titlecase in Unicode). This is the internal function implementing
          the "\u" escape in double-quoted strings.
  
          If EXPR is omitted, uses $_.
  
          This function behaves the same way under various pragma, such as
          in a locale, as "lc" does.
  
  ```
  
  # PORTING CAVEATS
  
  In future language versions of Raku, it will become impossible to access the `$_` variable of the caller's scope, because it will not have been marked as a dynamic variable. So please consider changing:
  
  ```
  lcfirst;
  
  ```
  
  to either:
  
  ```
  lcfirst($_);
  
  ```
  
  or, using the subroutine as a method syntax, with the prefix `.` shortcut to use that scope's `$_` as the invocant:
  
  ```
  .&lcfirst;
  
  ```
