 * transformed AST. The line & column numbers, as well as the character
 * offsets of each node in the ASTs derived from parsing the pre-transform
 * code & the equivalent post-transform code will not be the same.
 * Note that it is insufficient to pass in 'locations: false' into the acorn
 * parser as there will still be 'start' & 'end' properties attached to nodes
 * which represent character offsets.
