Why is tightly coupled bad but strongly typed good?

Question

I am struggling to see the real-world benefits of loosely coupled code. Why spend so much effort making something flexible to work with a variety of other objects? If you know w

Answer 1

strong typing will help reduce errors while typically aiding performance. the more information the code-generation tools can gather about acceptable value ranges for variables, the more these tools can do to generate fast code.

when combined with type inference and feature's like traits (perl6 and others) or type classes (haskell), strongly typed code can continue to be compact and elegant.
