First separator for subassignments must be '.' (issue 341490043 by address@hidden)

[thomasmorley65]

Even without your patch one can do:

part.1,1 = "foo"
part.1,2 = "bar"
part.1,3 = "buzz"
part.2,1 = "xx"
part.2,2 = "yy"
part.2,3 = "zz"
part.3   = "whatever"

#(format #t "\n\"part\" contains:\n~y\n" part)
#(format #t "Example call in guile: \"1\" of \"part\":\n~a" (assoc-get 1
part))
#(format #t "\nExample calls with ly-syntax:")

%% Working:
\void \displayScheme \part.2,3
\void \displayScheme \part.3

%% Causing errors:
% \void \displayScheme \part,1,1
% \void \displayScheme \part,1.1
% \void \displayScheme \part.1.1

I wasn't aware you can create nested lists with this syntax, already.

If I understand correctly your patch will disallow a first comma,
forcing a dot
Will it force the comma as second separator?
