Hello!
I don't think that `void foo() -> null` should be supported. Like in
lambdas if the method returns void, only expressions which can be used as
expression statement should be allowed. I don't think that special support
for empty bodies is necessary as {} is short enough. Especially if your
code style is not very bureaucratic and allows you to write `void foo() {}`
in single line.
With best regards,
Tagir Valeev.
