In particular, macros with "is parsed" will want to have a place to
hang their special parse rules without having to look up the macro name
twice. And when you think about it, maybe ordinary left parenthesis
is just stored as a circumfix macro with an "is parsed" rule of "expr".
Then circumfix:() and postcircumfix:() can automatically dispatch to
different locations. Likewise for {} and [].
