Hello folks,

I hope this is an easy question, but unfortunately some of the internals of MathOptInterface and JuMP are opaque. `constraint_object(constraint::ConstraintRef)`

operation in JuMP returns a ScalarConstraint, which has `.func`

and `.set`

attributes. I know how to evaluate the `.func`

, but I am still confused about how to confirm membership in the set (i.e. feasibility to the constraint). Here is a MWE.

```
using MathOptInterface
val = 18.
set = MathOptInterface.GreaterThan{Float64}(-2.)
# How do I confirm membership in the set, returning Bool, or distance from constraint boundary?
```

Thanks in advance!
