Nah. 99.9% of the people who wanted the addition of DryStructs to a codebase I worked on wanted it because they'd been bit, repeatedly, by someone sending one kind of object into a function rather than what the function accepted and it just not getting caught.

A robust type system allows you to make "compiler errors" out of runtime errors. One of these takes *way more tests to catch* than the other. I'll let you guess which.
