+### Sort existing use statements alphabetically
+
+If you do not know how to organize use statements, (or anything else, for that
+matter), the alphabetical order might be a sensible choice, because it makes

+if everyone adds new things at the same line, conflicts are guaranteed.

+    autocmd FileType php inoremap <Leader>s <Esc>:call PhpSortUse()<CR>
+    autocmd FileType php noremap <Leader>s :call PhpSortUse()<CR>
