My experience runs counter to this.  My employer has chosen to use
typing for every conceivable measurement. So we have type Meters, 
Meters_Per_Second, Feet, Feet_Per_Second, Seconds, Watts, Volts, and so 
on.
The list is endless.

To avoid conversions I would have to have hundreds of overloaded 
operators.
And to make matters worse, we have generic vectors that can be 
instantiated
for the basic types above.  I would have to have overloaded operators for
all the vector combinations.

No, using Ada in my problem domain, you are constantly converting types.
And it can be a pain.
