trying to conditionally load different versions of same plugins

foo.vim

for myplugin in ['yankmatches.vim', 'currentline.vim', 'cccp.vim', 'LS_COLORS.vim']
  let path = expand("%:~")

  " developing, use dev version of plugin
  if path =~ '\vdev[/]' . myplugin
    echo 'match!'
    let project_dir = fnamemodify(path, ":h:h")
    Plug project_dir

  " use stable version
  else
    Plug 'trapd00r/' . myplugin
  endif
endfor
