更好的Rebol语法比头部移除尾部（移除模具b）？

Question

我想将块转换为像这样的字符串

>> 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？

感谢。

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"}
