_if(function expression, function onTrue, function onFalse)

Return a handler, that on invocation will forward all its arguments together with a 'next' handler to [expression]. [expression] should then invoke its 'next' handler with either true or false. Depending on the result, either [onTrue] or [onFalse] will be invoked.

max(val1, val2, val 3, ..., valN)

Return the greatest value that was provided. Supports unlimited number of arguments.
