Is there a way to make a constant for a list of chars which I can use in a case statement? I’ve got a bunch of code duplication happening I’d like to clean up.

const
  TChars = ('[', ']', '(', ')', '{', '}', '=', ‘:’);

case c of
TChars:
...

I suspect you may need to use sets and the "in" operator.

   case c of
      '[', ']', '(', ')', '{', '}', '=', ':' : result := true;
   end;

That would be useful.

Only through macro ATM, I believe. Note that case statement body does NOT expect a set (it expects values, list of values and/or range of values), despite the very similar look (missing enclosing angle brackets only), hence the inability to do what you want.

Yeah I cheated and used a macro. ...and that’s why we should allow for macros as a fail safe in times of distress...
