on v1.0.1:

TYPES[expression.type] is not a function

I added a console.log to line 101 in index.js and got:

Node {
  type: 'ThisExpression',
  start: 1419,
  end: 1423,
  loc: 
   SourceLocation {
     start: Position { line: 54, column: 17 },
     end: Position { line: 54, column: 21 } },
  range: [ 1419, 1423 ] }

Perhaps the comment "This will map correctly for *all* possible expression types." above the function is inaccurate, and it should be explicitly handling unknown expression types?
