The answer to your question is "yes", but the loop I provided does the same
thing; it iterates over each array element. Sure, we could do without
introducing the extra 'arg' variable, but that's not the point you're making :)
By the way, the "wrong" loop in the script originally supplied ALSO produces
the expected output, but that should be considered another bug in ksh93. When
idx is explicitly declared as integer-typed and argtype is an array containing
strings, I would expect the following to fail:
typeset -i idx=0
for idx in ${argtype[*]}; do
print ${argtype[$idx]}
done
Why doesn't ksh93 (Version M 1993-12-28 s+) consider this (or even simply:
typeset -i idx="junk") an error?
