Confusion between type name and variant name shadowing

[wolfadex]

There are periodically users of Elm who write code like

type Change
    = Increment

type Increment
    = ByOne
    | ByTwo

and are confused that the type Increment doesn't correspond to the variant Increment. They don't realize that they actually need to write

type Change
    = Increment Increment

type Increment
    = ByOne
    | ByTwo

to get their intended result.
