class ILoop extends LoopCommands
The Scala interactive shell. This part provides the user interface, with evaluation and auto-complete handled by IMain.
There should be no direct dependency of this code on the compiler;
it should all go through the intp
reference to the interpreter,
or maybe eventually even over the wire to a remote compiler.
