,如手册所述:
-H Hide value: specifies that typeset will not display the
value of the parameter when listing parameters; the dis-
play for such parameters is always as if the `+' flag had
been given. Use of the parameter is in other respects
normal, and the option does not apply if the parameter is
specified by name, or by pattern with the -m option.
This is on by default for the parameters in the
zsh/parameter and zsh/mapfile modules. Note, however,
that unlike the -h flag this is also useful for non-spe-
cial parameters.
unset foo
typeset -A foo=([bar]=123)
echo $foo[bar]
typeset -p foo
123
typeset -A foo=( [bar]=123 )
