НА: Embedded Ela documentation - update is needed

[Василий Воронков]

I think it happens because of the layout based syntax; I'll take a look closer.

Thanks.

 Hi!

 

I tried to rearrange the "quick sort" algorithm in such a way:

 

qsort []      = []

// Using let-in form:
qsort (x::xs) = let lessThan = section (<)
                    notLessThan = section (>=)
                    section pred = qsort [y \\ y<-xs | y `pred` x]
                 in lessThan ++ [x] ++ notLessThan

//Using where form:

/*qsort (x::xs) = lessThan ++ [x] ++ notLessThan where
                    lessThan    = section (<)
                    notLessThan = section (>=)
                    section pred = qsort [y \\ y<-xs | y `pred` x]*/

qsort [2,1,6,1,6,8]

 

 

I see the message: "A conflicting definition of 'qsort'" If I toggle comments turning on the second variant, it works. Why does it happen?
