generic + numeric + literals = abomination

When writing generic FP code i always use real literals and cast to T, or int. I suggest doing this.
T exp3(T)(T x)
if (x < cast(T)(-1.15365L))
return cast(T)1.L + x * (cast(T)1.0L + x * (cast(T)0.5L + x * cast(T)0.3333333333333L));
I assume the compiler will be able to optimize the cast in release mode.
If you really wan't to prevent this cast in debug mode, you can simply go with:
const T myConst = 0.3L;
then the cast will be compile-time.
