Hmm, strange. Here's more irb interaction:
irb(main):001:0> :-
irb(main):002:0* .object_id
=> 548
irb(main):003:0> :-
irb(main):004:0* 1
=> 1
irb(main):005:0> :- 1
SyntaxError: (irb):5: syntax error, unexpected tINTEGER, expecting $end
        from X:/Ruby/bin/irb:12:in `<main>'
irb(main):006:0>

Notice how when I typed "1", it just discarded the :- on the previous line.

If I get around to it.

So Ruby and IRB are consistent in this respect. But I would still
expect Ruby *not* to wait for the next line when it encounters a
symbol like :- at the end of a line.
