First, i think we should answer to a simple question: why many other
computer languages allow underscores in their syntax as a
valid character for identifiers.
As to me, the answer is obvious: in natural languages we using space
to separate two words, and since parsers can't cope (or can, but its
highly impractical) with identifiers which having spaces:
my variable := foo.
an underscore is a good compromise between natural language and
computer language to separate two words,
while treat it as a single identifier:
my_variable := foo.
I came to smalltalk not long ago, and having over 15+ years of
I am always used underscores in this way, and never (or occasionally) like this:
_abdomination := foo.
Smalltalk spirit is a language which designed to remove unnecessary
barriers between humand and computer - easy to learn and easy to
express yourself, without need to be a highly educated
genius who can translate a natural human language to a cryptic sequece
of instructions which computer can understand.
And allowing underscores in identifiers, as to me, is highly coherent
with that spirit, because it this makes us easier to express
