- Optional arguments for tactics (feature seems to be good for everyone). We might want a more uniform syntax to "unconfuse" with attributes.
At least we need delimiters:
-
@tactic (opts)could be an option but would require two parsing rules per tactic -
tactic [opts]is a parsing nightmare (what if tactic takes an optional constr list after?) -
tactic #[opts]is maybe dangerous if users already have defined notations for #[ c ] in constrs. -
tactic @[opts]looked more innocent to us (@is already a keyword as well)
