Function Exits

It is often useful to be able to immediately return control from a function definition (like the C return statement). Jade's version of Lisp has the return function for this.

Function: return &optional value

This function transfers control out of the most-recent lambda-expression (i.e. a function or macro definition) so that the result of the lambda- expression is value.

(funcall '(lambda () (return 'x) 'y))
    => x

The 'y form is never evaluated since control is passed straight from the (return 'y) form back to the funcall form.
