The first thing I think you can do by adding a task callback manager
to print the value if the value would otherwise be invisible:
> h <- taskCallbackManager()
> h$add(function(expr, value, ok, visible) {if(!visible){print(value)};TRUE})
The semicolon thing would probably need rewriting bits of R at the C
code level.
I don't think many people would use it though. And my code above
might break things. I don't use it.
