Some mistakes should be committed just once.

Shameless self promotion, but I’m doing my part. Rendering Phoenix templates 12x faster (usual disclaimers apply: This is probably true for highly dynamic templates; my implementation is not yet complete, etc.)

Bonus: these new templates make it much easier to send diffs over the network for things like Drab, LiveView, etc.

I absolutely agree that dialyzer needs some love. I for one don’t insist on statically typed Erlang / Elixir because that would deprive us of a lot of goodies. But better warning messages and more intuitive way to work with specs is something that will push both languages into the future.

I am pretty sure it’s hard as hell but in any case, I believe it’s one pain point that needs addressed. Whether it’s in 3 months or 3 years, it was a soft-blocker for me and I had to persist a lot to gain a basic understanding and be able to use specs relatively well. And even now parameterizing the specs is something that makes me scratch my head. I might be stupid though.

Additionally:

• Standardizing Elixir’s configuration – compile-time, boot-time and run-time – is something that’s sorely needed to improve Elixir’s deployment story.

• Speaking of which, Elixir’s deployment with Distillery could benefit from less WTH experience – there’s a bunch of stuff to setup if you want to deploy to your own VPS and it’s easy to get it wrong. I am betting $20 that it will take me more than 15 minutes even if we don’t count the time to install everything needed on a VPS / droplet.
