Generics are dangerous

Generics are bad and complex and we should not have them.They make my head hurt. I don’t like complex. I like copying and pasting code and adjusting types. I like macro’s. Just like in 1981. You like generics? You support BUGS in CODE.

I haven't used generics all that much, but would it possible to have limited generics instead of generics being allowed for any types? Like let's say you wanted numeric generics, so you couldn't use blah<String>. You could only have blah<float>, blah<double>, blah<int>, blah<long>, blah<short>, blah<BigInteger> etc.
