I can't get parse error on that line but get other, on `end' line for
`for'.  This is since the previous line is `currentUser++', which is
parsed as [variable] [binary `+'] [unary `+'] so a token expected to
be the next is a part of some expression.  `end' is not so.

Ruby does not provide unary increment/decrement operators because they
don't fit Ruby's programming model.

Currently nothing but there're requests for more descriptive
messages.

This is OK but....

This is troublesome.

No gains without pains.
