ResTFlatMap(FuncT, Res) Method

Returns the error when IsErr; map(Unwrap()) when IsOk flattenning the result. Shorthand combining Map and Flatten calls.
C#
static Res<Team> TryGetTeam() { .. } // tries to grab a team; might fail, hence, returns Res.
static Res TryPutTeam(Team team) { .. } // tries to put the team; might fail, hence, returns Res.

Res result = TryGetTeam().FlatMap(TryPutTeam);
// equivalently:
Res result = TryGetTeam().FlatMap(team => TryPutTeam(team));

// this is a shorthand for:
Res result = TryGetTeam()   // Res<Team>
    .Map(TryPutTeam)        // Res<Res>
    .Flatten();             // Res
