Correct.  It does not affect regular command execution (and is not
intended to).

Those are two ways to enable PATH_SEARCH for a new zsh process,
sure.  Bart listed some more.

But "affecting future commands" is not really the way to look at
it; the option is not that general.  PATH_SCRIPT affects one very
specific behavior: whether or not ''zsh foo'' searches PATH for a
script "foo" if ./foo doesn't exist.  It does not affect anything
else, including PATH search *within* that script.

Probably should have asked earlier, but:  What were you trying to
achieve with PATH_SEARCH, exactly?
