There are two issues here that people seem to forget. First of
all, REBOL is based on values, not on "operators". So we are not
talking about adding a new operator, we are talking about adding a
new type of value, or at least adding new semantics for some
existing datatype when encountered by the function interpreter.
Second, there's something I don't like in the kind of semantics we
are talking about: we are hiding under some kind of syntactic
sugar an operation that is going to require an amount of
computation that is not evident by looking at the notation itself.
This is in part the case for paths too, so I'm not saying a firm
no
, but I'm very afraid of this kind of syntactic sugar.
Regards,
Gabriele.
