I normally use the separate-line version, just because I find it
easier to follow the same formatting nearly everywhere. I remember
someone (Beck?) giving similar reasoning somewhere about using "each"
as a loop variable, or "i" as a loop index - nothing to think about,
and you can recognize what's going on anywhere at a glance.
I do occasionally "break" this rule, though. For example, to:do: comes
to mind - I'll usually write
1 to: 15 do:
