Here's a link to the P2128 rebuttal draft:
n2740 Arguments against a[i...] syntax for multidimensional indexing
A bit long - here's a direct link to the Case Summary

The agenda looks quiet.
If there is interest I'd like to give a short presentation, ~10 mins, with arguments
against C++ proposal P2128 "Multidimensional subscript operator".
I'm writing a rebuttal paper for SG22 and could do with feedback before submitting it.
The topic is relevant to SG19 too, as it targets the mdspan API.
I'll post a link here.
