new Smalltalk programmer's thoughts

Hi Wolfgang,
Smalltalk, as an ambience, can be used
 for doing other activities than writing "programs"
 (aProgram, aComponent, or aModule).
When you compare Smalltalk with languages you are
 comparing syntax (the only thing comparable from
 a language perspective).
Newbies use to compare smalltalk from language
 perspective, or from OO way (through design,
 abstractions, patters) to the tools they used
 in the past.
Only with time, opportiunities of real use in production
 and contact with people that use smalltalk in another
 way (not simply like the best OOL); new ways of
 doing informatics emerges.
Smalltalk as a open system, let you do non-formal
 development (e.g. pass the limits imposed by
 formalization, reductionism & encapsulation).
As a non-formal device/medium, it is not the
 opposite of formal design; it is a convenient complement
 (the only one competitive complement to formal
 design used in software industry today)
best,
Ale.
