Module eager_or_lazy

Utilities for evaluating whether eagerly evaluated expressions can be made lazy and vice versa.

Things to consider:

• does the expression have side-effects?
• is the expression computationally expensive?

See lints:

• unnecessary-lazy-evaluations
• or-fun-call
• option-if-let-else
