Thanks to everyone participating in such a discussion so far, it's very
instructive. As for your comments above Elan, I know it is the way you
described. But, in such case, shouldn't we consider "", [] being datatypes?
->> datatype? ""
== false
->> value? ""
== true
hmm, it has a value ... so, if "" and [] are not considered being datatypes, it
is very strange, and as comparison to other languages I know (well, very few
:-), pretty uncommon, that we assign some word to the value, rather than value
to the word ....
