Weakly pure, yes - but for what?. Btw. I just gave a try at compile time 
evaluation of these hashes. I got rid of memcpy but then endianness 
issues arise. According to CTFE docs:

"non-portable casts (eg, from int[] to float[]), including casts which 
depend on endianness, are not permitted."

and the sad part is that hash source code involves endianness. So, there 
will be no compile-time hash support unless compiler would allow casting 
from uint[] to ubyte[] or uint* to ubyte*.
