> Another issue is that “-“ seems a little strange as a range token. “:” would match Verilog and some programming languages for more user familiarity.

"-" is a common math operator so it is not a very good range token ":" or "..." is probably better.

> I suggest using Dirac-style angle brackets to designate a bus definition, so a typical example might be "<nBL,A[8:2]>”. While I think a sufficiently aware gnetlist plugin could navigate this without the extra tokens, we’ve historically exploited the transparency of our formats to process schematics with other tools as well. The extra tokens will help.

Sound reasonable if special characters to not cause any issues.
