How to get word under the caret?

[schehlmj]

Other VSIX examples for finding the word under the caret use a ITextStructureNavigator, but how do I get that while using this Community.VisualStudio.Toolkit?

var docView = await VS.Documents.GetActiveDocumentViewAsync();
var point = docView.TextView.Caret.Position.Point.GetPoint(docView.TextBuffer, caret.Position.Affinity);

ITextStructureNavigator navigator = ....;  // how to get this?
var word = navigator.GetExtentOfWord(point).Span.GetText();

What would really be nice is a helper method...

var docView = await VS.Documents.GetActiveDocumentViewAsync();
var word = docView.TextView.GetWordTextUnderCaret();
