Hello,
I know there are several important differences between let-expressions and where-clauses regarding scoping and the restriction of "where" to a top-level definition. However, frequently I write code in which either one would be allowed, and I was wondering if there were any guidelines or preferences for one structure over the other. Currently my choice is guided by aesthetics more than anything else ( I prefer the look and ordering of a where clause). Is there anything else I should consider? What do veteran Haskell programmers prefer?
I prefer the expression style. And I also like to order my definitions in a file "bottom-up" (basics first). But it may be more didactic to do it all "top-down". Imports should be placed at the bottom of the file then, too. My cent, Christian
