What types of new missions do you want?

I'm going to try to write a handful of missions. What types of missions do you want?

(1) Python language: Simple missions that help with parts of the Python language where Checkio is not currently heavy. E.g. exception handling, decorators, generators, etc.

(2) Puzzles: Graph theory, combinatorics, algebra

(3) Puzzles: Other

(4) Puzzles like Chicken Hunt, Ghost Ship, etc.

(5) Series of problems that help introduce a programming or mathematical concept, with hard puzzles to follow (Linear Programming comes to mind.)

(6) Golfing

(7) Other
