string - 如何在同一规则中混合字符串解析和 block 解析？

Question

Rebol 的 PARSE 方言足够泛化，这很酷，它可以对符号结构以及字符串进行模式匹配和提取。像这样:

; match a single "a" character, followed by any number of "b" chars
>> string-rule: ["a" some "b"]

>> parse "abb" string-rule
== true
>> parse "aab" string-rule
== false

; look for a single apple symbol, followed by any number of bananas
>> block-rule: ['apple some 'banana]

>> parse [apple banana banana] block-rule
== true
>> parse [apple apple banana] block-rule
== false

但是假设我正在寻找一个包含苹果符号的 block ，然后是与字符串规则匹配的任意数量的字符串:

; test 1
>> parse [apple "ab" "abbbbb"] mixed-rule
== true

; test 2
>> parse [apple "aaaa" "abb"] mixed-rule
== false

; test 3
>> parse [banana "abb" "abbb"] mixed-rule
== false

我如何制定这样的混合规则？查看文档，它建议人们可以使用 INTO:

看似自然的答案似乎不起作用:

>> mixed-rule: ['apple some [string! into ["a" some "b"]]]

虽然它通过了测试 1 并在测试 3 中正确返回 false，但在测试 2 中错误返回 true。这是我的错误还是 Rebol 中的错误(我正在使用 r3 A111)？

史蒂夫在 REBOL3 forum建议这样做:

only the second string is checked.
Should be:
    ['apple some [and string! into ["a" some "b" ]]]
