Hi, Gregg,

IANARTE  (I Am Not A REBOL Technologies Employee... ;-) but I suspect
that data types are entangled with the lexical scanning performed
by LOAD.  IOW, it might be necessary to provide a specification for
how to recognize values of a new datatype at the lexical token level,
and that might not be convenient/feasible...

Just a guess!
