It's not special -- omitting it would have exactly the same effect as
omitting a colon does today in a single-line statement. That is, today you
can write
if x < y: x = y
or you can forget the colon and write
if x < y x = y
and (usually) be diagnosed by the compiler. My proposal would make
if x < y:
x = y
and
if x < y
x = y
have the same meanings as (respectively) the first two examples above, so
the fourth example would still be diagnosed as an error for the same reason.
