I also think that nim could use a "memory" module with defines a mem-slice and
different pointer arithmetic procedures (and a real hexdump function). That
would at least set a standard on how to deal with raw memory for whatever
reason. This also could have something like `proc MemSlice(s: string):
MemSlice` which uses `unsafeAddr(s[0])` and `s.len`. This is of course unsafe
and people may use it wrong but it would unify the topic in a module which
could hold some information about Nims data types internal structures and why
and how stuff works different to what one may think how it works. Those
"MemSlice" could then be the universal Parameter for procs which accept memory
buffer/len pairs.
