"while" comes to mind.

Well, yes.  I should've included while and the like.  But you can't use a FF
in "foo = /flip/ .. /flop/":

irb(main):013:0> foo = /flip/ .. /flop/
ArgumentError: bad value for range
        from (irb):13

So ".." and "..." behave differently in a context like "if", "unless",
"while" etc.

Hope that cleared it up.
