You can not generalize that far. Most programming

Nope. See http://en.wikipedia.org/wiki/Smalltalk
Just checked. Smalltalk's colons seem to have completely different
semantics. Correct me if I'm wrong, but they appear to be at the end
of every keyword, including ifTrue and ifElse.
There are some differences between making commas
optional and making
trailing colons optional.
"There are some differences between making X optional and making Y
optional" for all features X and Y.
This generalization is meaningless. You deliberately ignored the
Clearly the use of the specific semicolon character
you. So let's replace it with a better symbol: \n as in this example:
for i in x: foo(i) \n bar(i+1)
Sure a \n is optional at the end of any line because a blank line is
always allowed. So what?
What's the point you are trying to make?
