Description
Very frequently in math, given an object (say divisor) D and an equivalence relation D~D', we denote the equivalency class with [D]. I think it would be cool if we could define methods on [T], for instance:
[Divisor] := D -> -* the class of D in the class group *-
How hard would this be?
Related: #1978
As a potentially far fetched extension, allowing (a,b] and [a,b) to produce half open intervals would be useful (both [a,b] and (a,b) work fine and can be interpreted appropriately by methods, so that's not a concern).

Research direction
No files, tests, or entry points are named. Start by reviewing related issue #1978 and the existing behavior described for [a,b] and (a,b); then identify the notation-handling entry point and define tests covering [T] methods and the proposed half-open intervals.
