Hi Tom,

Thanks for scribing!

For the following:
Hubert: For those few who perhaps use $ in the preprocessor in C and C++ code, until recently, their code was formally ill-formed.
Hubert: I don't have a lot of sympathy for UB in such strange uses.

I suggest:
Hubert: For those few who perhaps rely upon $ being standalone non-identifier tokens in the preprocessor in C and C++ code, until recently, their code was formally ill-formed.
Hubert: I don't have a lot of sympathy for people who rely on the exact manifestation of UB in such strange uses.
[later observation by Hubert]: Due to longstanding divergence between C and C++, the "formally ill-formed" (and corresponding UB) was only true for C++ but not C. As an extended character in [at least certain vintages of] C, $ always could have been a standalone preprocessing token or one of the implementation-defined identifier-nondigit characters.

For the following:
Hubert: Use of $ as a macro name would be impacted.

I suggest:
Hubert: [context lost/unclear] Use of $ as a macro name would be impacted.

Thanks again,
