trap doesn't accept / ignore --

11. BUG: trap doesn't ignore --

I can find similar behavior for eval though I haven't checked the other builtins. In Bash, when one needs to pass an arbitrary value to trap / eval, one needs to specify -- because, for example, command=--help; eval "$command" will not be interpreted as expected.

$ osh -c 'trap "echo hello" INT'
$ osh -c 'trap -- "echo hello" INT'
  trap -- "echo hello" INT
          ^
[ -c flag ]:1: Invalid signal or hook 'echo hello'
$ osh -c 'eval -- echo hello'
  -- echo hello
  ^~
[ eval at line 1 of -c flag ]:1: '--' not found
