It seems that D would benefit from having a standard syntax format for
expressing various range sets;
a. Include begin Include end, i.e. []
b. Include begin Exclude end, i.e. [)

d. Exclude begin Exclude end, i.e. ()
I'm afraid this would majorly mess with pairing of parens.
I think Derek's point was to have *some* syntax to mean this, not
necessarily the one he showed (which he showed because I believe that's the
"standard" mathematical way to express it for English speakers). For example, we
could say that [] is always inclusive and have another character which makes it
exclusive like:
a. Include begin Include end, i.e. [ a .. b ]
b. Include begin Exclude end, i.e. [ a .. b ^]
c. Exclude begin Include end, i.e. [^ a .. b ]
d. Exclude begin Exclude end, i.e. [^ a .. b ^]
I think Walter's message really rendered the whole discussion moot. Post of the
year:
=========================
I like:
a .. b+1
to mean inclusive range.
=========================
Consider "+1]" a special symbol that means the range is to be closed to the right
:o).
What about bearophile response: what about x..uint.max+1?
How often did you encounter that issue?
