You can assign (write only) to the global scope of the current
subshell using `declare -g'. It sounds like you want something more
than that. Bash doesn't provide a longjmp-like construct and it's not
possible to run code from another context without returning.

You can walk the stack in ksh93 with the debug trap, but setting
.sh.level then modifying state is extremely fragile. I'm sure it would
be the same deal in bash, though it has no equivalent feature yet.
