description	Guides for Haskell code. Use when writing Haskell code.

• Annotate fromIntegral with both TypeApplications
• Avoid defining functions by cases on their last argument, use LambdaCase
• Avoid list indexing (!!)
• Avoid partial functions (head, undefined) except in tests
• Instead of nesting Either, Maybe, and tuples, make a new data type
• LambdaCase now supports \cases for multiple arguments
• Never return tuples of arity higher than 2, just make a new data type
• Never use unsafeCoerce or unsafePerformIO
• Only use Either for error handling, otherwise make a new data type
• Use Data.Text.IO for I/O
