Actually you can:

== c
or if the path is referenced by a word
>> p: 'a/b/c
== a/b/c
>> type? :p
== path!
>> third :p

or if the path is in a block

== c
The trick is to prevent evaluation of the path in the same fashion as with
functions. Also you can convert between paths and blocks.
>> to-block :p
== [a b c]
>> to-path to-block :p
== a/b/c
