Hi “Anon”,
A more serious answer (though just personal opinion) is that your idea
lacks the “grammar” that it implies.
Value Relationship Value “a >= 99”
is a “sentence” or fragment in most computer languages. It is a logical
assertion that is either true or false and can be composed into larger
sentences in that grammar.
99 <= a && a <= 123
What your “value range” notion is saying is not just “99 or more” but also
“is in the range of 99 or more”. The “in the range of” is implied in
addition to the + as “or more”.
a 99+
It feels empty of the relationship even if 99+ has the range meaning.
Compare:
a in 99+
That feels clearer to me. Both concepts are now made explicit. The language
Pascal has ranges and a membership clause. ADA also embraced some of it. We
could imagine:
a in 99..
a in 99..123
The “in” part feels important to me.
