It doesn't, except when they're used as parameters for method calls.  
Basically, the return type was stored in a slot in the symbol table for
each function (defaulted to object, IIRC).  It was therefore an additional
couple of tokens to parse, and a little bit of additional information in the
symbol table that the OO symbol resolution code used.
