  • Computer Programming for Everybody

    ...Global undo is similar to what version control provides, where system level changes can be tagged and rolled back when they adversely affect the system. Where global undo differs however is that no a-priori decision has to be made about tagging. We also plan to enhance the development environment with type-checking tools that help programmers find mistakes in their code and improve the performance of compiled code. Python is a dynamically typed language, like Smalltalk or Scheme, that rel...

Scripting languages have become incredibly popular, and an advanced scripting language like Python makes a good starting point for our expedition. One persistent criticism on scripting languages is that their performance is inadequate for some tasks.
