@epatters @mehalter, I came up with this approach for computing with linear relations. It relies on the idea that a LinRel `f:R^n-R^m` can be stored as a basis of a subspace in `R^{n + m}`. If this is…

I was expecting that it would be possible to wrap a wrapped/grouped relation within a gateway relation and have it execute the correct SQL (maybe by using unwrap/ungroup internally?).
If this poses n…

```
i = Symbol("i", integer=True)
n = Symbol("n", integer=True)
expr = And(Eq(i, 2 * n), Le(i, 2*n -1))
```
I would expect that `expr.simplify()` yields `False`, but it does not.

Maybe it is my unfamiliarity with working with NamedTuples but I found it awkward to get a subset of columns when I was porting my DataFrames code to use TypedTables. I came up with the following fun…
