compilation of seq_pushback.cpp attachment

It may seem like the compiler would generate a copy CTOR; however, compilation of the seq_push_back.cpp attachment give the compile errors shown in the seq_push_back.compilation attachment.

The reformatted error message in compilation attachment is:

seq_push_back.cpp:48: error: No match for ' boost::fusion::joint_view < boost::fusion::list

< boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_

, const boost::fusion::single_view<int>

::joint_view

( boost::fusion::joint_view

< const boost::fusion::list

< boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_ , boost::fusion::void_, boost::fusion::void_

, const boost::fusion::single_view<int>

which shows the copy CTOR was not used because it didn't match the 'const list<...>' part of the argument. Maybe the problem is with the result_of<push_back<,> >::type?
