Huh? Methods are just subroutines by another name.
Yes, there is a (single) difference (polymorphism). Everything else is
old hat: parameter passing (with an additional implicit 'self'
parameter), local variables, synchronous call/return sequence, recursion
etc.
This was one of my initial grudges against Smalltalk: Lots of new words
meaning just the same old stuff, making it difficult to understand what
was really new about Smalltalk. Just try it:
Smalltalk terminology Standard terminology
method subroutine
message send subroutine call
object data structure
self first parameter
I concede there are important differences, and a different set of
concepts. But some Smalltalk-80 books said that the difference is in
methods and messages, and that's just not true; these concepts may have
been designed to be different but turned out to map quite clearly to
well-established concepts.
