c++ - Why does this private template function compile? -> Compiler Bug VS 2009 -

-

this compiles out problems in vs 2009? stupid? gcc gives warning, template private....? missing?

#include <iostream>  using namespace std;  class { private:     template<typename t>     a& operator<<(const t & v)     {         cout << v << endl;         return *this;     } };  int main() {    a;    << 4;    system("pause"); }

microsoft acknowledges bug , claims fixed in next major release compiler (which read vc11/vs-whatever-is-after-2010 - not service pack vc10/vs2010):

from comments, fix appears made internal compiler build.

-
what put in vim config? how change it? i want .html extension...because html... i think need au bufread,bufnewfile *.ejs setfiletype html au short autocmd docs it's idea put inside test if has("autocmd") au bufread,bufnewfile *.ejs setfiletype html endif to avoid error messages if ever use cut-down version of vim doesn't support feature. finally, if have default filetype rule like: au bufread,bufnewfile * setfiletype text then *.ejs rule must above it.
