#Haskell list comprehension code

Don't leave trailing white space in your code in every line.80 character lines is considered good practice across IT industry and supported in all cases. If the expression is longer than 80 lines, try to structure & rewrite the code in a more expressive way. Code with short lines reads casually and easier to understand. Lines should not be longer than 80 (preferably 75) characters.multi-parameter type classes (MTPC) and functional dependencies (FD) the code becomes 'non-portable (MPTC with FD)'.

#Haskell list comprehension portable

Try to write portable ( Haskell 2010) code.

Make sure that the description is changed to meet the module (if the header was copied from elsewhere).

The following hierarchical module name must, of course, match the file name.

All Haskell source files start with a haddock header of the form:.

Put a haddock comment on top of every exported function and data type! Make sure haddock accepts these comments.

Also, try to avoid putting comments inside a function body: if the function is so complex that you need to separately comment parts of it, you should probably Generally, you want your comments to tell WHAT your code does, not HOW.

Comments should be written using correct spelling and grammar in complete sentences with punctuation (in English only):.

Don't use technical terms - that's what the code is for!

Comments are to be written in application terms (i.e.

4.10 Implementation-specific extensions and classes.
