But I don't find it evident from that document that Int32+Int32 gives Int64
on a 64-bit machine!
I am investigating possible data structures for an application.
Here is an interesting behaviour in IntSet, which is no doubt to do with
the implementation.
Maybe it should just throw an exception if someone tries to add a really
large integer like this!
julia s = IntSet()

Ah, that's a neat solution, thanks!

I need to iterate over a Set whose elements will be deleted in the process.
However, some deleted elements are included in the iteration, e.g. the
element 4 in the code below.
Is this a bug, or am I misunderstanding?
Thanks.
julia s = Set(5, 3, 4, 6)
Set{Int64}({5,4,6,3})
julia for i in s

This was just changed on master so that you'd do Set([i*2 for i in 1:5]).
OK, that seems reasonable, thanks.

OK, I think I have answered my own question: a Set is the good structure.
And to create a set from an array I can do something like
s
ecosystem!
Thanks,

But without more information, these might all be wrong (or inefficient) for
your problem. :-)

Hi,
Suppose I have the following:

I can select a single element of the array r using
r[3, 4]
Now suppose that I have the position [3, 4] stored in a variable as
pos = [3, 4]
How can I use pos as the index for selecting the *single* element r[3, 4]?
I would like to do r[pos],
