I agree, but as an experienced user, I nevertheless prefer switch and 
restore over checkout, because those are rather different tasks, and 
with checkout you're only ever a small thinko and errant dot away from 
losing your local changes. If switch and restore had existed first, I 
don't think anyone would be asking for mashing them together.

Incidentally, as reset is similarly overloaded, and restore can also 
replace the forms of reset that take pathspec arguments, was there a 
similar plan to factor the head-moving forms of reset out into a 
separate command? (I realise there'd be little appetite for that after 
the switch/restore experiment.)

Thanks. There's also the checkout.guess variable as a closely related 
precedent.
