V2 (ppxlib.Ppxlib.Driver.Instrument.V2)

val make : 
  (Expansion_context.Base.t ->
    Ppxlib_ast.Parsetree.structure ->
    Ppxlib_ast.Parsetree.structure) ->
  position:pos ->
  t

Same as Instrument.make, but the transformation that will be applied to the AST has access to an expansion context. To be used together with Driver.V2.
