This class represents a StringSwitch like class that is useful for parsing expected keywords.
On construction, unless a non-empty keyword is provided, it invokes parseKeyword
and processes each of the provided cases statements until a match is hit. The provided ResultT
must be assignable from failure()

Case that invokes the provided functor when true.
The parameters passed to the functor are the keyword, and the location of the keyword (in case any errors need to be emitted).
