Hi, it's a bit unwieldy to write/read this:
result = src[base .. base+size];

result = src[base, size];
Maybe such syntax would be a welcome addition to D? I don't see 
it conflicting with the existing grammar, and only the 2 
slicing-operators need further extending to support it.

If this is a common pattern in your code, you could write your 
own function to do this and call it using UFCS:

    Range slice(Range)(Range r, size_t base, size_t size)
    {
        return r[base .. base+size];
    }

    auto arr = [0,1,2,3,4,5,6,7,8,9];
    assert(arr.slice(4,2) == [4,5]);
