map repeat macro command @@ malfunction

[dohsimpson]

I tried to map @@ to repeat with @ only:

call submode#enter_with('repeat_ex_cmd', 'n', '', '@@', '@@')
call submode#leave_with('repeat_ex_cmd', 'n', '', '')
call submode#map('repeat_ex_cmd', 'n', '', '@', '@@')

It would enter submode and works find as long as I stay in submode. But when I exit submode and try to use @@ again. I would get something like this inserted at the beginning of my buffer: ubmode-enter:repeat_ex_cmd). And I would be put into insert mode.
