It's... weird. M-x doesn't work inside 'C-x C-f', but it does work 
inside 'C-h f', for example.

That seems like a bug, one way or another.

Emacs allows us to redefine basically everything. But there's a 
meaningful difference between forcing the user to call a magic command 
to enter the "dragon land", and having that command by default in the
