`with` construct usage question - variables in `else`

@gregvaughn

It can be done with wrapping tuples

I see.Thank you. Didn’t think of that. Maybe because

@gregvaughn

it’s ugly

indeed

@gregvaughn

If you find yourself in that situation, then it’s probably worth stepping back to look at the bigger picture for other design approaches

Full ACK. Thanks once more.

Not quite

Quite literally in fact

@stefanchrobot

What about the suggestion to introduce a unified error struct?

This comes later in the article section and it is very much OK. In fact similar to what I am used to do in other languages when justified. Here, I may not yet be as well-versed in Elixir as I am in numerous other languages but when I am confronted with a well confined piece of not-really-reusable business logic I rather take a dozen lines of the author’s perfectly readable “Bad Elixir” than the larger, more complex and less readable “Good Elixir” I think the else was added to the language at some point for a reason. And the fact that it actually enforces matching the failed expression is for a reason too. Obviously this shouldn’t be abused to create monstrous blocks of rather brittle code - that would be a completely different story.
