I keep forgetting that construct exists!
Thanks! (Sorry for the late reply… busy busy.)
But does the construct truly do anything but open a new scope?
Like, let’s look at the example in the docs, and rewrite it:
opts = %{width: 10, height: 15}
if true do
{:ok, width} = Map.fetch(opts, :width)
{:ok, height} = Map.fetch(opts, :height)
{:ok, width * height}
end
I have no elixir environment at this computer, but this should be the equivalent, right? Or did I miss something?
[EDIT: I guess the else block for failed matches is of course awesome.]
Could you please give me an example of how you would rewrite a nested case-do statement so I get a better idea of what you’re aiming at?
