Another possibility is to use `.A`: the (.) prefix means the symbol is
looked in the external scope, not inside the template. So the 2-params A is
found.
template A(T)
{
alias .

In D the overloaded operators need to be defined inside

Yes, it's possible:

I'm trying to parallelize some code which is essentially a network of
cells with an index. I can make the cells immutable, if I route all
access to them via the index, AND if I can update the index. The index
would not need to have items deleted, but updates would cause it to
point to differe

Then how can I approach this to work for both cases:
1) output is empty?
2) output is the size of input? (MmFile's)
You have to tell those cases apart with a run time test, so your
output range should support empty, or even length. If you want to
overwrite the already allocated space, t

But isn't output empty?
Indeed it is, when output is a new array.
Then how can I approach this to work for both cases:
1) output is empty?
2) output is the size of input? (MmFile's)

The code below works as is with memory mapped files' casted
opSlice's.
However, I can't figure out how to test it with simple arrays.
Its unittest fails.
Question:
How to implement the function correctly?
Otherwise what is the correct way to test it?
Thank you.
Code:
Range2 c
Hi,
could someone tell me what the problem(s) with the following are?
Also, how do I make "$" work with the slice operator?
Thanks a lot.

Graph opSlice(uint start, uint end)
