Some thoughts.

Provide only bitwise comparison, search etc. It's the only case that can 
reliably benefit from SIMD or hand-written ASM, has problem with CTFE 
support, etc. Then requiring that T be a POD or built-in type is fine IMHO.

Maybe go for copy ---> rawCopy, find --> rawFind (i.e. model after 
std.algorithm) rather then mimicking C functions. This way we are open 
to a superset of C-runtime ;)
