I have a question about the _describe builtin.
I am building a binary that provides dynamic completions using a completion
function.

Is to possible to provide completions to _describe that will be matched not
only on the text of the completion but also on words/text in the
description? Or, is it possible to turn off completion matching entirely
and have zsh present the user with a verbatim set of completions provided
to compadd or _describe? Thanks in advance!
