I think, it's perfectly sensible for arithmetical types like Integer. If you
mean “the next integer” then succ n is the most logical thing to write. If
you write n + 1 instead, you invoke a more complex operation (addition) with
a special constant as one of its parameters, and this obfuscates what you
actually mean, in my opinion.
