stored procedures?

[ear7h]

Hi, again! I'm messing around with cozo again and came up with an interesting problem. I've created a web of named queries like:

allowed_users[principal, email] := ...

allowed_channels[principal, channel_id] :=
    *channel{author, ...},
    allowed_users[principal, author], ...

allowed_threads[principal, channel_id, thread_id] :=
    *threads{channel_id, thread_id, author, ...},
    allowed_users[principal, author],
    allowed_channels[principal, channel_id], ...

I'd like to use these as part of implementing GET /users, GET /channels, GET /threads, etc. That is, these queries will just be filters for a queries against *user, *channel, and *thread. As far as I can tell, I'll just have to duplicate this text for each query. But, is there a way to save these queries like function/stored procedure?

Something that has the shape of what I want is fixed rules, and the registration mechanism. However, fixed rules must be implemented in complete isolation to the Db.

Currently, we also just duplicate this kind of stuff so stored named rules could be really useful for sure
