Hi,
There's a fair amount of information missing from this post that makes it difficult to have a meaningful discussion about the proposed addition.
This message briefly summarizes the evolution process for DocC and links to several pitches/proposals—from both people who contribute to DocC frequently and people who are first time contributors—that you can use as inspiration when writing your own pitch/proposal.
At this stage in the discussion, the implementation is less relevant. Instead, it would be good to focus the discussion on:
What is the problem statement that this is solving?
How does the proposed solution solve that problem?
Details about any user-facing syntax that the proposed solution would introduce
A brief description of one or more viable alternatives and why the proposed solution solves the stated problem better than those alternatives
Any open questions that need to be discussed where the pitch/proposal doesn't make a specific recommendation.
Please update your proposal to have a short section for each of those topics so that it's easier for the community to discuss the proposal.
