Your name-rule requres a let-char then it permits for none and then goes to
end. In both ERR! cases let-char is fulfilled, then at some point the none
part of the following bracket is fulfilled and then to end is performed. No
wonder you end up with true in both cases. Compare to:
>> parse "abcdefg" [none to end]
== true
