print value instead of stdout to the output

Hello,

I looked for a similar issue before I written this one (was sure someone else would purpose this) but couldn't find any.

Anyway, the suggestion is really simple: as far as I can tell, the current implementation runs the script and at the end of the execution delivers whatever is on the stdout.
However, one of the most important features (IMO) of live programming is the ability to view the value of most expressions on your code at any given time. of you can add some language specific print and then see the value but that's a bit tiring after a few evaluations.

I suggest to deliver the **value** of the expression to the output.
