Just a sanity check...
I've been studying Grid.jl <https://github.com/timholy/Grid.jl> and one of
the neat tricks there is to inherit from AbstractArray, which allows us to
write our own getindex. However, the indices are not integers. I like this
trick enough I am considering making it a common structure when dealing
with "arrays with additional info". At one point, I also got this
deprecation error and it made me nervous.
Although non-integer indexing is deprecated, am I still allowed to do it if
I build my own getindex? Or, put another way, will Grid.jl still work?
Thanks.
PS: I am finally starting to do some real modeling with Julia and I have to
say that although it is sometimes tough for my aging grey matter, when I do
get something to work the experience is intellectual satisfying. Kudos to
the Julia development team. This is a programming language "done right".
