Programming Language Thoughts

What makes a good programming language?

A good programming language is expressive. That means I can easily turn the thoughts of my head into code. A good programming language is easy to read. It's important for code to be read because code lives. Others edit it, extend it, learn from it. A good programming language is fast.

GRR Rails

I am learning Rails.

Here are the things that make me go GRR

1. I see code like this MyModel.like "apples". Is there any documentation on that? or did someone write the method like? Is there a cool way to do likes relationally?

//the terms "late binding", "dynamic binding", "polymorphism" kind of blur together for me
//here is an example of this concept in Go


package main

import "fmt"

type Animal interface {
  Say()

drewlesueur

// run this code at http://golang.org/
package main

import "fmt"

type Person struct {
  age int
  name, fav_band string
}

# link with an extra property .__meta
# or each object has a .__uid that links
# if you are going to have an extra property anyway, why not make it the meta property.
meta = {}
get = (scope, variable) ->
  if scope.__meta.get?
    return scope.__meta.get scope, variable
  else
    return scope[variable]

Javascript wishlist

• Tail Recursion optimization. (Allow loops with recursion.)
• explicit scope access. How do I add variables to the scope? window[varname] = val, scope[varname] = val Similar to the this variable is like an extra parameter that is the object that has the function. The scope could represent the current scope. (has all closure variables)
• Being able to explicitly assign a function to a scope. Explicit closures.
• Proxies, or something similar. (some sort of meta syntax) possibly http://brendaneich.com/2010/11/proxy-inception/ Maybe something like
