Read again:
The “syntax class” of a character describes its syntactic role. Each
syntax table specifies the syntax class of each character. There is no
necessary relationship between the class of a character in one syntax
table and its class in any other table.
So whether { resp } have the syntax class symbolised by ( resp. ) depends
on how you set up your syntax class table. Major modes set that up to match
the expectations of the language in question. In theory you could even set
# . up as opening and closing parentheses whenever it makes sense.
The answer is: Emacs _already does_ what you want.
Cheers
