As said in the other email in this thread this doesn't seem to be a
bug (like script coding error) ...
... how would a possible solution look like and not break things like this...
-- snip --
typeset -a ar=( a1 b2 c3 )
nameref n=foo
for n in "${ar[@]}" ; do
print "$foo"
done
-- snip --
... where the nameref "n" just aliases a single variable used in all
for-loop passes (and not multiple ones like in Aaron's example) ? How
should a solution work if all this is done dynamically, e.g. using
"if" statements which re-declare the nameref "n" between loop passes ?
