Methods of the module object
Returns a term that is functionally equivalent to
t is of the form
((y1, ..., yn) => e2)(e1, ..., en)
then it optimizes this the top most call by returning the
with the result of beta-reducing the application.
To retain semantics the argument
ei is bound as
val yi = ei and by-name arguments to
def yi = ei.
Some bindings may be elided as an early optimization.
