This specific problem has been on Bugzilla for ages: 
https://issues.dlang.org/show_bug.cgi?id=14835 . It went nowhere 
because no one could figure out a reasonable way to make the 
compiler apply the warning *intelligently* in generic code, and 
there was no consensus to remove the current broken version, 
because it is still useful in non-generic code.

This issue also killed efforts to improve various aspects of the 
compiler's handling of integer comparisons (twice):
