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 use let in monadic code and in lambda expressions, and where clauses everywhere else, pretty much. It's pretty much entirely based on what I think "looks" nice. -- Sebastian Sylvan +44(0)7857-300802 UIN: 44640862
