This doesn't work in the general case anyway, because the output of
"typeset -p" (aka "declare -p") doesn't properly reflect local scopes.
That is, if you're in a local scope, sourcing the "declare -p" output
will create all the variables at that local scope, not at the scopes
where they were originally defined.

In fact it's impossible to correctly reconstruct the local and global
scopes because of the runtime dynamic scoping rules.
