This is essentially where I'm going with ix. Vim with an awesome haskell-like language underneath whose syntax is optimized for doing powerful stuff in command mode.

A prototype is at https://github.com/jayferd/ixl-prototype

Re:The worst thing about CoffeeScript on Saturday January 25, 2014 @07:06PM (#7123120)
I don't know if this can be solved without a syntax change. As long as there is variable binding and variable mutation are conflated in the syntax, there's really no good way for the compiler to distinguish between the two. It's an unfortunate design decision that we may be stuck with if we want back-compat.

LiveScript is interesting, but seems to have Too Many Features for my tastes.

That's up to you. Maybe that will become more clear as you see the social power imbalance more clearly. Perhaps your framing of the whole situation would change, I don't know.

Please stop. This attitude is offensive to both men and women.

Re:Sexism and Tech and Love on Wednesday December 18, 2013 @02:27PM (#6929944)
Yes, turns out it takes some effort to be aware of power imbalance and work against it. Those words have different social meanings when spoken to a woman than when spoken to a man.

Re:C is Lower Level Than You Think on Tuesday November 26, 2013 @02:48AM (#6799758)
This is a problem in most imperative-paradigm languages, unfortunately. The issue is in the semantics of the `for` loop, which make everything confusing both for the programmer and the compiler.
Re:How to design a class on Friday November 22, 2013 @05:48PM (#6784262)
What's really missing though is unions with destructuring `case`. Once you start coding in a language with proper unions, it's hard to go back. In python it might look something like this:

    DataType = union({ 'type1': ['field1', 'field2'], 'type2': ['field3'] })

    DataType.type1(val1, val2)
    DataType.type2(val3)

    # pretend syntax
    case datum:
      DataType.type1(a, b):
        doSomethingWith(a, b)
      DataType.type2(c):
        doSomethingWith(c)

These look an awful lot like homes to be calling the people living in them "homeless". I wonder what it would look like if the city didn't keep bulldozing them?

Re:HTML.js – Befriend the DOM on Tuesday August 13, 2013 @05:34PM (#6208397)
I'm not sure what you mean by "cases where the return value type is actually unknowable". Does that mean you only return an Element when it's something for which there can be only one on the page (like document.body)?

As far as APIs go, one way would just be to return a list always. The DOM, afaik, returns a special NodeList thing that isn't even an array. ( https://developer.mozilla.org/en-US/docs/Web/API/NodeList?re... ). What's the actual issue with using wrappers?
