... and shift key pressed and released once.

... and possibly pressing C-g to exit the transient keymap.

That solution has a number of limits:

1. it is not general, you have to define specific keys for each case

2. the keys that are bound are not self-inserting anymore, you may have to 
exit the transient keymap manually with C-g

3. there are even cases where this is not possible to use it, for example, 
how would you repeat C-x C-t?

4. you cannot freely change the argument between two repetitions
