When would one want to use Tuple indexing? Would that be used in conjunction with MTKParameters?

[AayushSabharwal]

No, just allowing the parameter object to be a Tuple: ODEProblem(fn, u0, tspan, (1.0, 2.0, 3.0))

Let's follow up with the performance bit if it's needed.

[AayushSabharwal]

This can't really be fully inferred, since

1. The dict in the last argument is not concrete
2. The type of the buffer can change

Gotcha
