Debugger: display code being executed

Can the debugger please print out the code that is executing to the terminal?

Ideally it would include a little context:

> so
Paused at file main.lua line 13

local c = function(x) {
==> if stuff then junk() end
}
Bonus points for commands to display context above/below the current line
