As a rule thumb, when the type "S" is an input range, than so is "S*". Indeed,
all of "S's primitives" can also be called using a pointer, EG:
S* p;
p.popFront(); //OK!

This works for *all* input ranges... except for slices. This is because the
"slice range primitives" are actually non-member functions:
int[]* p;
p.popFront(); //DERP!
Error: template std.array.popFront does not match any function template
declaration

I think, to be consistent with the "emulate a member primitive", that the range
functions in std.array should also work on pointer to slice.
