For POSIX, we really ought to be accepting the -p flag which displays
the listed parameters but in a different format (in the form of a
typeset command). This typically being -L in zsh has probably been
significant in this not being done before. It might actually be a good
idea to add -p as an alternate form of -L across many builtins.
One possibility which is an extension of (3) would be to make it only
work on typeset but not for all the other typeset variants and then follow
bash in changing the documentation so declare is the recommended version
of the command (it's a better name anyway in my opinion). The
KSH_TYPESET option could be extended to make typeset also work that way
for ksh compatibility. Additionally, we could perhaps add a flag to
typeset and variants which could explicity control whether set parameters
A related annoyance - autoload being a sort of typeset variant - is that
autoload ~/.zfunc/*(N) will not end silently if there are no files in
~/.zfunc. Changing this could perhaps be a part of whatever solution is
