in the following "<<a <<b", the solution code tries to get <<a to work first and then fails with "parsley: two input redirects.", whereas mine fails immediately after seeing <<a and <<b. Do we need to make our code also first do a here document for <<a, and then fail? 

Example I ran "<<a <<b". I immediately wrote an "a" when prompted and then got an error.
