I've also discovered that multiple statements on one line need to
be separated by a semi-colon in the REPL, as in:

Number factorial := method(n := 1; for(i, 1, self, n = n * i); n)

I tried the above w/o them and got stung!

So, newlines in the REPL notwithstanding, it seems that it's
there's multiple statements - separate them with a semi-colon.

I've also discovered that the newlines *in a script* serve as
statement separators. However, again, if the statements are all on
one line, the semi-colons are required. I gotta learn the hard
way, it seems. lol ...

It takes some getting used to - but then again, what doesn't! I
wish that I was a faster keyboarder - I'd join in on IRC....

Thanks!
