I don't understand what is meant by "grouping variables". Do anonymous
braces do anything at all when applied around variables?
Scad:
{ a = 1; b = 2; cube();}
{ c = 3; d = 4; sphere();}
AST:
a = 1;
b = 2;
c = 3;
d = 4;
cube();
sphere();
CSG:
group() {
cube(size = [1, 1, 1], center = false);
sphere($fn = 0, $fa = 12, $fs = 2, r = 1);
}
They look like they do nothing at all to me.

The anonymous scopes was a design mistake in early OpenSCAD, where scopes
didn’t have a function.
I don’t know how often people use that feature to group variables, so I
haven’t dared changing that yet, but I do agree that ideally this should be
a true scope.
Deprecating assert() was indeed a bit premature, but it functions well as
a way of telling people to avoid using it.
The parallel assignment behavior was an extra motivator to deprecate it.
Adding let() makes sense to me and that would also be another baby step
towards OpenSCAD2 :)
