This is really just an else: right? I think it's better to do it that way. If due to some bug it tries to append something to None it will fail loudly instead of continuing silently.
Moreover, at 1st glance this made it look like the dims has a secondary function here as a way of signalling where we are in the token processing when in fact it isn't: we're either at the beginning [, the end ], or it's something to append. I think? I'm tired, so... 😅

dims actually does have that secondary function! The tokens also contain stuff before the first [, and we want to ignore them. A quick debug print reveals it:

Ah, right! I guess I should have tested it.
Not sure I'm a fan, it may be a bit too clever. But tests are failing on my side (probably some update, I hadn't picked this up in a while), so I won't be volunteering any alternative right now.
It's quite readable anyway, it's 👍 from me.

I'm always eager to merge after seeing the thumbs up... but just double checking, by "a bit too clever" you mean the details of the implementation (which can be improved later), not the idea?

Hey, sorry I thought I had replied to this. Yeah, I meant the implementation with regards to the use of the dims variable and such. But again, it's totally readable so I think it's fine.

Merged now anyway, thanks!
In preparation for upcoming changes, store array dimensions in a list while parsing types.
In most cases, magic values for array dimensions in documentation are meaningless, and the symbolic name in code is desirable. Try to parse the symbolic names from tokens.

The force push was just a rebase because there were conflicts. |
Things like
get documented with the actual value 5 rather than the symbolic
SIZE. Fix it.(This includes #184 to ensure it works at all.)
