Curried Closure

Partial application in PHP:

<?php
  use Nassau\CurriedClosure;

  $closure = new CurriedClosure('explode');
  $imploder = (new CurriedClosure('implode'))->curryLeft("\t→ ");
  $dashed = $closure->curryLeft('-')->compose($imploder);
  $dotted = $closure->curryLeft('.')->compose($imploder);
  $dotted3 = $closure->curryLeft('.')->curryRight(3)->compose($imploder);
  
  $array = ['1.6.9.4', '1.0-dev', '2.x-aplha', '3.5-RC1'];
  print_r([
    'dashed'   => array_map($dashed, $array),
    'dotted'   => array_map($dotted, $array),
    'dotted-3' => array_map($dotted3, $array),
  ]);

Outputs:
