Re^2: Avoiding if/else knots

My approach to that problem would be to write function to map the input to the keys in the hash. Something like

$dispatch{calculate_key{$input}}->(%attr);

sub calculate_key
{
  #..
  return $key;
}

holli, Sure except that calculate_key() is going to contain the same if/elsif/else knot that the OP is asking to avoid. The bottom line is that if your conditions are not exact keys then using dispatch tables will not avoid the knot. That isn't to say that it can't help make the code cleaner. Cheers - L~R	[reply]
