// touching the Method's Node (through the left edge, see below) which is something the user probably
// didn't want since they specifically selected only the return type.
//
// What the selection is touching is used in two ways.
// - Firstly, it is used to handle situation where it touches a Token whose direct ancestor is wanted Node.
// While having the (even empty) selection inside such token or to left of such Token is already handle
// by code above touching it from right `C methodName[||](){}` isn't (the FindNode for that returns Args node).
// - Secondly, it is used for left/right edge climbing. E.g. `[||]C methodName(){}` the touching token's direct
// ancestor is TypeNode for the return type but it is still reasonable to expect that the user might want to
// be given refactorings for the whole method (as he has caret on the edge of it). Therefore we travel the
// Node tree upwards and as long as we're on the left edge of a Node's span we consider such node & potentially
// continue traveling upwards. The situation for right edge (`C methodName(){}[||]`) is analogical.
// E.g. for right edge `C methodName(){}[||]`: CloseBraceToken -> BlockSyntax -> LocalFunctionStatement -> null (higher
// node doesn't end on position anymore)
// Note: left-edge climbing needs to handle AttributeLists explicitly, see below for more information.
// - Thirdly, if location isn't touching anything, we move the location to the token in whose trivia location is in.
// more about that below.
// - Fourthly, if we're in an expression / argument we consider touching a parent expression whenever we're within it
// as long as it is on the first line of such expression (arbitrary heuristic).
// First we need to get tokens we might potentially be touching, tokenToRightOrIn and tokenToLeft.

// didn't want since they specifically selected only the return type.
//
// What the selection is touching is used in two ways.
// - Firstly, it is used to handle situation where it touches a Token whose direct ancestor is wanted Node.
// While having the (even empty) selection inside such token or to left of such Token is already handle
// by code above touching it from right `C methodName[||](){}` isn't (the FindNode for that returns Args node).
// - Secondly, it is used for left/right edge climbing. E.g. `[||]C methodName(){}` the touching token's direct
// ancestor is TypeNode for the return type but it is still reasonable to expect that the user might want to
// be given refactorings for the whole method (as he has caret on the edge of it). Therefore we travel the
// Node tree upwards and as long as we're on the left edge of a Node's span we consider such node & potentially
// continue traveling upwards. The situation for right edge (`C methodName(){}[||]`) is analogical.
// E.g. for right edge `C methodName(){}[||]`: CloseBraceToken -> BlockSyntax -> LocalFunctionStatement -> null (higher
// node doesn't end on position anymore)
// Note: left-edge climbing needs to handle AttributeLists explicitly, see below for more information.
// - Thirdly, if location isn't touching anything, we move the location to the token in whose trivia location is in.
// more about that below.
// - Fourthly, if we're in an expression / argument we consider touching a parent expression whenever we're within it
// as long as it is on the first line of such expression (arbitrary heuristic).
// First we need to get tokens we might potentially be touching, tokenToRightOrIn and tokenToLeft.
