Always false float comparisons

[Walter Bright via Digitalmars-d]

Don Clugston pointed out in his DConf 2016 talk that:

     float f = 1.30;
     assert(f == 1.30);

will always be false since 1.30 is not representable as a float. However,

     float f = 1.30;
     assert(f == cast(float)1.30);

will be true.

So, should the compiler emit a warning for the former case?
