Just for the sake of clarity: "{" and "}" have never been "forbidden" in
Pd message, you just cannot /type /them.*)

discussions are always more limited.
The thing in the way now is wether "{" and "}" should be officially
incorporated with a new syntax, like nested lists. There are arguments
against as in the last message by christof here and I agree and think
we could just let "{" and "}" be supported as regular characters and
that we can expand the usage of dollar signs for expanding Pd's
syntax, like ${ and $}
And, also, I'd like to point that there are forks of Pd that actually
already allow "{" and "}"... I can see why one would disregard this,
but it's something worth noting. You can already do this in PlugData
and PurrData/Pd-L2ork, and the patches actually work and are already
compatible to Pd Vanilla.
I also don't see an expansion of the language syntax coming up very
soon or easily, so just allowing "{" and "}" could be good to at least
get this issue out of the way, since it's been bugging people for edge
cases for ages.
What do you people say?
cheers

Well, they have not been forbidden. You can not *type* them (yet),
but
they can appear in text files or in manually assembled symbols. In
fact,
they are properly displayed with [print] or list/symbol atoms, which
suggests that they are already properly escaped when sent to the GUI.
One could argue that someone who only uses libpd might not even be
aware
of this issue.
Curly braces have never been a part of special Pd symbols (semicolon,
colon, dollar), so I'm sceptical that we can just give them some
meaning. It would break lots of existing code that uses symbols with
curly braces. For example, it would completely break the
"purest_json"
library.
However, we could use *escaped* curly braces. The escape sequences
"\{"
and "\}" are not defined, so we might use those for nested lists. I'm
not saying it's pretty, though.

Anyway, it's a bit silly that we still can't type curly braces, given
how important they are for many use cases. I mean, I cannot even
type a
JSON string...
