DATATYPE
NOTHING! value
N.A.
Not applicable on category
NOTHING! When a type mismatch is detected, it detects if one of the parameters is NOTHING! (UNSET! in REBOL) and then assumes that this is the cause and reports that. In Meta, NOTHING! (UNSET! in REBOL) is a truthy value, whereas in REBOL it's FALSE. Not much else has been revealed about this datatype.
To be done.
