Hum, seems to be not fixed, I got this error
* _vimrc: *
autocmd BufEnter *.cpp,*.hpp,*.h,*.c call that.UnderLineHeaders()
*_autoload/myhelper/myhelper.vim: *
*export def UnderLineHeaders*(): void
echomsg 'UnderLineHeaders called for buffer ' .. expand("%:p")
some stuff....
if !exists('*g:OpeningHeader') # not enough to prevent the error above
* def g:OpeningHeader*(): void
some other stuff
*enddef*
*enddef*
