It's 'Smalltalk' one word and lower case t :)
The idea is that if you write the code in proper English you achieve a
couple of things:
1) The only necessary comments are the description at the top of a
method. Your English is self documenting the code.
2) Very short methods. If a method is longer than 1/2 of a screen this
means you cannot visually see your logicall without jumping up and
down. The language doesnt even have a case statement and the
ifTrue:ifFalse: is actually a method similar to inline ifs we have in
PHP.
3) You can write what could take you 5 lines of code on one line. You
just read left to right including the math (there is no operator
precedence).
So it was necessary to have standards including case sensitivity to
make the coding concise.
