Great!

Look at the INTO keyword in parse.
>> b: ["hello" [world]]
== ["hello" [world]]
>> parse b [string! word!]
== false
>> parse b [string! block!]
== true
>> parse b [string! into [word!]]
== true
>> b: [hello [world]]
== [hello [world]]
>> rule=: [set w [into [word!] | word!] (print mold w)]
== [set w [into [word!] | word!] (print mold w)]
>> parse b [some rule=]
hello
[world]
== true
HTH!
