Nested lists would be awesome!
There has already been a discussion on GitHub:
https://github.com/pure-data/pure-data/issues/505.
I've tried to argue that we shouldn't suddenly reclaim existing valid
characters. Instead we could extend the semantics of $ to allow for more
control sequences.
In that sense, I have suggested to use ${ and $} instead of plain { and
} as nested list delimiters.
Similarly, we could finally support $@ as a placeholder for all
arguments or even introduce argument slices like $[1:4].

this.
and while this was shot down when I proposed it back then, I still think that
using curlies for nested lists would be the simplest solution.
