1. It does not have yet :-) Though I hope to have that bit finished soon.
2. We have to jump though hoops in order to implement accurate variables
display despite the fact that stepping though the function can cause
new variables to come into scope, possibly shadowing previously visible
variables. This of course is not very efficient, but I hope to implement
proper mechanism in GDB to handle that.
