I played with the toplevel a bit, but was frustrated by the limitation
of one-liner input.
Even in an interactive toplevel it is nice, I think, to be able to
write multiline programs.

The simple solution is to make ";;" mandatory, which clearly delimits
the end of user input (instead of considering all 'enter' as end of
input). The tryocaml toplevel is however very lenient regarding use of
";;", and I suppose this is a deliberate design choice.

I have implemented an heuristic to allow multiline input, based on a
past discussion with Nicolas Pouillard about, if I remember correctly,
Scala's toplevel behavior. The idea is to accumulate lines of input
until the parser either succeeds, or there is a syntax error; when it
just consumes all the line without producing a result, we wait for
more input.
Patch attached.
