# TODO: Should this be static?  Calling `system_profiler -listDataTypes` takes

_data_types=( SP{AirPort,Applications,Audio,...(snip)...,WWAN}DataType )
# the dynamic alternative is:
#_data_types=( ${${(f)"$(_call_program path system_profiler -listDataTypes 2>/dev/null)"}[2,-1]} )

At least on macOS Ventura (the latest), "system_profiler -listDataTypes"
gives somewhat different list of data types. And I think the time
required by this command is negligible (I can't notice any delay).
So isn't it better to use the 'dynamic alternative' in the above comment?
