Hmm... maybe the [throw] attibute could be used for that too...
RT?
Currently it does not work because the SWITCH function is no more
special than your function; REBOL just know that the code that
produces an error is running "inside" the SWITCH function.
Maybe the solution would be to include a full stack dump instead
of just providing the topmost function name. I.e.:
a: func [] [make error! "Bomb!"]
b: func [] [a]
c: func [] [b]
should give out:
Where: [c b a]
or something like that.

Maybe we could just write a REP and send it to Carl? I think
having a pointer in error/near and a stack dump in error/where
should be rather easy to implement for RT.
