Include both input & output redirects in $words during completion

How can I configure zsh to include input & output redirects in $words
during completion?

They were not included when I looked at $words.

I'd prefer if the <, >, <<. >>, or other redirect was a separate
element in $words, followed by a separate element for the
source/target of the redirect, regardless of spacing. e.g., <in & < in
would both produce a $words with separate < & in elements.

Thanks for any help.
