The result is:
C:\ark\gcctest>g++ -I c:\boost\boost_1_32_0 a.cpp c:/boost/boost_1_32_0/boost/mpl/find.hpp: In function `void X::foo()': c:/boost/boost_1_32_0/boost/mpl/find.hpp:29: error: `template<class Sequence, class T> struct boost::mpl::find' is not a function, a.cpp:8: error: conflict with `template<class T> void X::find(const T&)' a.cpp:13: error: in call to `find'
As you can see, the parameter to foo() makes the compiler consider the boost::mpl namespace for ADL. The combination of unqualified call and g++ finding class templates during ADL produces the error.
According to GCC's bugzilla whether this is wrong is an open Core issue http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17365 I'm not sure which DR Gaby is referring to there, possibly 405 ? This is why GCC hasn't been "fixed" to ignore the non-function. jon -- "You have attributed conditions to villainy that simply result from stupidity." - Robert Heinlein
