Yes, something like that.

I am not sure how the configuration parser currently works and what
are the implications of adding this syntax.

But having a shorthand

set root.branch {


set root.branch.value1=key1;
set root.branch.value2=key2;
set root.branch.value3=key3;

is good for several reasons. At the very least it reduces typing,
enhances readability somewhat, and allows for more modular
construction of multilevel menus or such.

apt uses :: for separator (not .) and any :: can be replaced with {
and has to be closed with } then.
