It is non-portable, since some hardware architectures may use 
different representations (e.g. different byte order on int and 
float).

D claims to follow C, so using unions for type punning is 
ultimately implementation defined.

In C++ using unions for type punning is illegal/undefined 
behaviour, so in C++ you should use memcpy. Memcpy also has the 
advantage of explicitly copying thus avoiding some aliasing 
issues.
