I use static typing to do as much as it can do.  I'm currently coding
in C# and am frustrated because collections are not type-safe so one
is constantly downcasting.  You have to pay for strong typing without
getting the full benefit.  In C++ I could go for months without
writing any dynamic cast.

I used to value it highly, but have recently changed my opinion and
value the ability to rapidly switch between coding and testing more
highly.

It's useful, but as implemented in Ada, and to almost the same extent
as implemented in C++, it's also expensive.
