How many D programmers acquire data from sensors that require 
such default language-integrated fault detection?
Versus how many D programmers would be well benefited from having 
floating point types treated like other numeric types, and 
sensibly default initialize to a usable 0 value?
Why is one group determined to be the one that needs its use case 
catered to, and not the other?
