https://dlang.org/spec/type.html#usual-arithmetic-conversions

This defines a series of possible conversions used to bring two expressions to the same type for arithmetic operations. This set of conversions is mentioned for equality expressions, among others. However, the spec doesn't mention what happens when those conversions fail. I guess it's undefined behavior?
