Nim may include a simple linear equation solver in the future to help us
infer static params when arithmetic is involved.
The Nim compiler includes a simple linear equation solver, allowing it to
infer static params in some situations where integer arithmetic is involved.
Just like in regular type classes, Nim discriminates between ``bind once``
and ``bind many`` types when matching the concept. You can add the ``distinct``
