Comments

  • Hash merging

    This function also works for hashes.
    def $a = hash('a', 'b')
    def $b = hash('c', 'd')
    def $c = $a|merge($b)
    


    will make

    $c['a'] = 'b'
    $c['c'] = 'd'
    


    Very useful for growing hashes iteratively. However, bear in bind that hashes cannot have numbers as keys! I lost an hour trying to figure out why my
    foreach
    
    didn't work. :-)
  • foreach containing a merge

    .. of course my foreach contained a merge.
