Things i think need improvement

• Diagrams
• GHC error messages
• Haskell Cookbook
• Haskell explained to the busy
• Mac OS X

Chlor

• Haskell SVN
• Objective-C SVN

• SVG

Todo

• EPS export

• SVG export
  • SvgPath

    • <path d="M 100 100 L 300 100 L 200 300 z" fill="red" stroke="blue" stroke-width="3" />

  • SvgRectangle

    • <rect x="400" y="100" width="400" height="200" fill="yellow" stroke="navy" stroke-width="10" />

• SVG XML generation
  • HStringTemplate?
  • HXT?
  • HaXml?

• Shape
  • Sine (Box, phases)

Why?

• to add a structure
• to reduce redundancy
• to make scanning easier:
  • why scanning
  • first two words
