Questions about that proposal are often risen on the list.
Some think that we will still be able to supply () argument
to () -> T functions.

To clear that up completely, I suggest adding this grammar change
to SE-0066 or one of the newer proposals. Key idea is that parentheses
are part of function type grammar and have nothing common with tuples
or unit type.
