How to use dynamic sources in consult--multi

[lrustand]

I'm trying to use a dynamic source in consult--multi, but it doesn't show any results from the dynamic source, only the static ones. If I put the same dynamic source in consult--read instead, it works flawlessly. Is there something that has to be done differently to make it work inside of consult--multi?

EDIT: I was mistaken about the "doesn't show any results" part. It actually throws an error, see next comment.

Actually, it doesn't just silently fail. (I had mistakenly not unquoted it when adding it to the list). It actually returns the following error, followed by a whole lot of gibberish: Wrong type argument: plistp, #[257.

I previously had a call to consult--multi that looked like this:

(consult--multi '(source-a source-b source-c))

Now, because of performance issues in source-c I have converted it to a dynamic source that looks like this: (consult--dynamic-collection #'generate-some-strings). Using this dynamic source like this works as expected:

(consult--read (consult--dynamic-collection #'generate-some-strings))

But adding it to the original multi source like this fails with the above error:

(consult--multi `(source-a source-b ,(consult--dynamic-collection #'generate-some-strings)))

Dynamic sources are currently unsupported by consult--multi.

Why? And will they be supported? I feel like this is a major drawback

Dynamic sources have been discussed before and are planned. Unfortunately it is not easy to integrate them into the existing infrastructure in a consistent way.
