I don't remember any reply to the message you quote above, which
summarizes my current thinking and position. As you indicate, it is
a question of making a decision.

Global Maintainers: What do you think? Let's make a decision so that
Walfred can resume his work on this.

Thanks!

> I think using commas systematically is making it worse for ourselves, since it prevents us from using gdb_buildargv to parse the command arguments for us. Commas also have a meaning in C, so arguably they could be used in expressions as well. But, if that's the way people prefer, then having a standard gdb_buildargv-like API that everyone consistently uses will make it easier for me to accept that decision.
