I find the optional parentheses, and the way that keyword lists are defined to be the two biggest stumbling blocks when I come back to Elixir after a while way.
Coming from other languages, I find that
example("with", 3, extra: "arguments", as: "a", keyword: "list")
being equivalent to
example("with", 3, [extra: "arguments", as: "a", keyword: "list"])
and
example "with", 3, extra: "arguments", as: "a", keyword: "list"
always takes some extra mental effort to get through, especially when there's no parenthesis. But I appreciate not having to write all the extra brackets and parens when I get going, so I think it's a fair tradeoff.
- arcanemachiner 5mo agoElixir has enough syntax sugar to cause diabetes. Personally, I like the flexibility, but yes there are a lot of rules to keep in mind.
