Replace "as much as possible" with "the bare minimum provided by the 
compiler", and you will be usually right :-)

Managers rarely choose languages like Haskell or Ada(?) where programs 
can be provably shown to be correct. They choose languages with just 
enough compile-time type checking to get in the way of rapid development, 
but not enough to lead to actual correct code. 

Some want languages like C that offer type-checking, but not languages 
like Pascal and its derivatives which enforce that type-checking -- 
Pascal is a "bondage and discipline" language, while C lets you escape 
from the discipline of types with the freedom of casts and other 
dangerous weak-typing features.
