Now-a-days we often write
auto f(...)->decltype(expression) { ... return expression; }

I propose to drop the result type:

auto f(...) {... return expression; }

but on two conditions:
(1) only if there is only one return in the function body (a bit similar to
a newly proposed lambda);
(2) you are not allowed to refer to this function using a header (forward
declaration, etc).

The second option will guard against the abuse of the usage.

I find it looks ugly, when a long expression is written in the decltype
construct.

I think this feature may be particularly useful when writing templates.
