3310,Why hasn't Ticket #1890 (1.35) been dealt with? It is still current: RE: boost::python embedding tutorial.,kat@…,Dave Abrahams,"Ticket #1890 is 15 months old.  The ""python embedding tutorial"" is still screwed up (""1890"" was at version 1.35).  There are a host of blog entries on the web about this problem (and essentially no fixes, and few new boost-users would understand enough to get through this problem): basically
on the webpage: http://www.boost.org/doc/libs/1_39_0/libs/python/doc/tutorial/doc/html/python/embedding.html

object ignored = exec(""hello = file('hello.txt', 'w')\n""

    ""hello.write('Hello world!')\n"" ""hello.close()"", main_namespace);

should be:

object ignored = exec(""hello = file('hello.txt', 'w')\n""

    ""hello.write('Hello world!')\n"" ""hello.close()"", main_namespace, main_namespace);

As described in ticket #1890.

This cost me > 2 hours, and I could have written my python interface from C++ using calls to ""extern C"" python API in significantly less time than that (and I haven't even seen the API before).  Clearly a better default parameter setting for exec's parameter ""local"" would be the incoming value of ""global""?
