Rebol 语法比 head 删除 back tail（删除模具 b）更好？

Question

我想将块转换为这样的字符串

>> b: [field "field1" tab field "field2"]
== [field "field1" tab field "field2"]
>> head remove back tail (remove mold b)
== {field "field1" tab field "field2"}
>>

有比这更好的语法吗？

谢谢。

模具/仅应该可以解决问题：

b: [field "field1" tab field "field2"]
mold/only b
== {field "field1" tab field "field2"}
