#10733: [wave] Hooks not called for expanding specific predefined macros

     Type:  Bugs                                   |     Status:  new
Milestone:  To Be Determined                       |  Component:  wave
  Version:  Boost Development Trunk                |   Severity:  Problem
 Keywords:  hook, predefined macro, expansion      |
---------------------------------------------------+---------------------
 Non of the preprocessor hook is called during the expansion of the
 following predefined macros: {{{__LINE__}}}, {{{__FILE__}}},
 {{{__INCLUDE_LEVEL__}}}.

 This is because the expansion of these macros are handled with a specific
 code path which skips the hooks.

 Expected behavior:
 * expanding_object_like_macro hook is called before the expansion
 * expansion happens based on the return value from the hook
 * expanded_macro hook is called after the expansion
