Scaladoc [use case]
Some methods on ScalaDoc API have their descriptions preceded with [use case]
. However, I can't find them on the source code, and they don't make sense sometimes. For example,
def +: ( elem : A ) : List
is a variance violation, since lists are co-variant.
So, what does use case
mean, why are their type signatures suspect sometimes, and why don't they appear in the source code?
As a bonus point, are they described somewhere on the Scala language site?
