Yes, but not in irb; in irb, after you type "foo \n", it is
immediately evaluated.

irb should also treat symbols that way -- and not halfway interpret
them as operators. (I say "halfway" because on the one hand it waits
for the next line, as it would with a dangling operator; but on the
other hand, it then just throws away the symbol and evaluates the next
line as if it stood alone.)
