Now I understand that keys separated by periods, for example, StaffGrouper.staff-staff-spacing.basic-distance = #7 is a way to access a nested alist easily.

gamme.1 is not a variable name. It takes gamme to be an alist, and the
entry under key 1 is what is addressed here.
Since you showed the Scheme equivalent below, I guess the above is a part of LilyPond syntax, or something the LilyPond parser does. Is that documented elsewhere? I’d like to know a bit more details.
Best regards,

Not really in an obvious place, but there is some text here: https://lilypond.org/doc/v2.22/Documentation/notation/modifying-alistsBest, Jean
