Options/configs for something. Imagine that instead of going with binary flags you can pass in [read, write, {encoding, "utf-8"}, {buffer, Size::Int, Delay::Int}] as a list of config options. Makes for readable stuff.

It's nice because you can use similar stuff for TCP sockets like [raw, keep_alive, whatever] and merge that list with SSL options like [{private_key, "some data"}, {cipher_suites, ["AES-...", "ECDHA-..."]}, {sni_hostname, "example.org"}, ...] and have it work together. I guess you would enumerate all the possible combinations in your type signature if you really wanted to, you're just not forced to do it in a dynamic lang.

A couple pages late, but you can do this in Haskell with GADTs.

code:

data OptName a where
  Read :: OptionName Bool
  Write :: OptionName Bool
  Encoding :: OptionName String
  Buffer :: OptionName (Int, Int)
  -- ...

infixl 1 :=

data Option where
  (:=) :: OptName a -> a -> Option

opts :: [Option]
opts = [Read := True, Write := False, Encoding := "utf-8", Buffer := (32768, 100)] -- and so on.

You can probably make a better type for storing the options than a list.

If you really want to be able to specify names at run-time, I think there are ways to do that as well, using open coproducts, but that's a type of magic even I don't understand yet.

I just learned today that Nim ignores n-dash characters in identifiers too. Which is doubleplusbad because it's the m-dash that should be used without spaces.

is there a hipster relational query language that is like sql but good?

no, because what plain SQL is good for is for interoperability, or "please dear god i don't want to write any more analytics or reporting by hand, from scratch"

quote:

i've been hitting cases of things that should be easy but turns out to require bolt-on-feature x that is only supported in some random 25% of sql servers

someone must have made something based more on relational algebra and less on cobol

they did, postgres, and then they dropped quel and added sql to get postgresql

i mean its execution engine isn't as good as Oracle's but if you get to the point where you need a single monster database server for your business then you should maybe think about scaling out instead if possible idk

if you remove the "let", its 10000 false every time.

you know when people say that JavaScript is getting better all the time, what they're actually saying is the transpilers are. implementations of JavaScript aren't moving that fast at all. what in gods name is that let declaration doing to the scope of those brackets to bring that out of the VM?
