 """ Lexer for PPAPI IDL
 
 The lexer uses the PLY library to build a tokenizer which understands both
 WebIDL and Pepper tokens.

For bonus points, could you replace this resource-leaking open() with a |with|

with open('test_parser/inline_ppapi.idl') as test_file:
    ...test_file.read()
?

Thanks!
