                       java.util.Stack l)
Description copied from interface: Function
Evaluate a function and return the resulting scalar. Only the sleep interpreter should ever call this function. If you have a maddening desire to call this Function object yourself, then use the convienence method in SleepUtils.

Specified by:
evaluate in interface Function
Parameters:
n - the function being called.
i - an instance of the script calling this function.
l - a stack containing the locals passed to this function. The locals are Scalar values passed in reverse order i.e. [arg n, arg n-1, ..., arg 1, arg 0]
Returns:
an instance of Scalar containing the return value of this function.
