"Stop throwing errors in your library! They cause my app to crash"

Who amongst us hasn't hear of the popular maxim: "Fail late even after you know something is wrong, and then make sure the failure cascades over the whole app in mysterious ways"

My dev lead is a uniquely poor leader with an impressive ability to produce a large amount inflexible, temporarily functional code.

As we're in another pair programming session where I try to keep him from destroying over all type safety and architectural decisions to meet a self imposed demo deadline, he keeps trying to access properties of his state.

This state object is incorrectly typed with an anonymous type with incorrect properties.

Despite repeating calmly stating that the object is incorrectly typed, and that's why there are red underlines when he tries to access a property he knows is in there, he insists that that's not correct.

Finally, he knowingly says that he's figured it out and that he's been doing this for many years.

What was the solution you might ask? (state as any).myProperty;

Truly breathtaking mastery.
