The KWATZ! datatype is used for values, which are not recognized as being of any known datatype.

This can be utilized for example in dealing with UTM Coordinates.
LOAD can load anything:

w> block: load "17T 630084 4833438"
== [#{313754} 630084 4833438]
w> type? block/1
== KWATZ!
w> to string! block/1
== "17T"
w> type? block/2
== integer!

So it's easier to make dialects, that for example can deal with numbers with units, like:

w> Earth: load "radius: 6,371.0km mass: 5.9736e24kg"
== [radius: #{362C3337312E306B6D} mass: #{352E393733366532346B67}]
w> type? earth/1
== set-word!
w> type? earth/2
== KWATZ!
w> parse Earth [some [set w set-word! set k kwatz! (print [w form k])]]
radius 6,371.0km
mass 5.9736e24kg
== true

The KWATZ! datatype works much like the binary! datatype and can be converted to e.g. binary! or string! for further parsing.
