Code written in cucumber syntax is concise and easy to read

concise |kənˈsīs|, adj.

giving a lot of information clearly and in a few words; brief but comprehensive.

Compare:

Scenario: Defining the function foldl Given I want do define foldl Which has the type (in brackets) a to b to a (end of brackets), to a, to list of b, to a And my arguments are called f, acc, and l When l is empty Then the result better be acc Otherwise l is x cons xs Then the result should be foldl f (in brackets) f acc x (end of brackets) xs

To:

foldl :: (a -> b -> a) -> a -> [b] -> a foldl f z [] = z foldl f z (x:xs) = foldl f (f z x) xs

How is that more concise or preferable?

I thought it was a joke. Roman
