This simplifies a lot of code. On the other hand, this does not change the prior semantics of terminator detection, which means that if any whitespace is taken before <.eat_terminator> is called, a final '}' won't be recognized as terminating a statement. This commit also turns a few "\s*" heavy places and changes them from 'token's into 'rule's, and overall prefers <.ws> to \s*

Try doing this:
$ bin/007 --backend=i13n examples/name.007
Should get this output:
# static frame #1
# call A from line zero: frame 2
# static frame #3
# call B from line zero: frame 4
1. macro name(expr) {
# static frame #5
# call C from line zero: frame 6
2. if expr ~~ Q::Postfix::Property {
3. expr = expr.property;
4. }
# static frame #7
# call D from line zero: frame 8
5. if expr !~~ Q::Identifier {
6. throw new Exception {
7. message: "Cannot turn a " ~ type(expr) ~ " into a name"
8. };
9. }
# static frame #9
# call E from line zero: frame 10
# call F from line zero: frame 11
10. return quasi { expr.name };
11. }
12.
13. my info = {
14. foo: "Bond",
15. bar: {
16. baz: "James Bond"
17. },
18. };
19.
20. say(name(info)); # info
21. say(name(info.foo)); # foo
22. say(name(info.bar.baz)); # baz
