(I have good news for you :-)
Smalltalk is an evolving environment, then if you change
it in any way it will continue been Smalltalk. :-)
Evolution is the property of a system to change
anyway to continue been "alive" (evolution preserve identity).
It is the main difference between an evolving system
and a programming language.
If you cange a syntax in a minimal way... it will not
be the "same" syntax (the change does not preserve
formal rules defining the language).
In an environment (where evolution can be observed and not simply change)
the identity of the system is preserved and not it internal properties nor
As an example:
A better language than C can be C++ (C++ is NOT C).
Smalltalk is defined as an object environment, then a better smalltalk is an
smalltalk with better objects (it continue been the SAME object environment,
[inside smalltalk you can find a lot of objects specified
using a syntax, also named Smalltalk :-( ]
Object Technology let us leave the languages (and formal methods)
to start handling open systems development.
In an object environment we can use formal expressions
define objects (work object oriented) and observe
the emergencies of the resulting virtual system
to learn differences with natural/physical systems
without defining them as objects (not all things are objects).
