Nimrod's builtin slices copy. It's possible to implement more 
D-like slices in Nimrod, but a bit tricky. However, if you don't 
copy slicing a large string (or array) keeps the whole string in 
memory so it's questionable whether it's a good idea.

D implements slices as (ptr, length) pairs which causes issues 
for a GC as that invites lots of interior pointers and GCs tend 
to have problems with those, causing at least some overhead in 
the GC/memory system.
