bytes!(..).to_owned() does not work in statement position

[lilyball]

The expression bytes!("foo").to_owned() works when placed in an expression position, as in let x = bytes!("foo").to_owned(). However, it does not work in a statement position, as in just bytes!("foo").to_owned() by itself:

error: unexpected token: `.`
 bytes!("/bar").to_owned()
               ^

Looks like env!() has the same problem. I'm guessing this is common to all normal syntax extensions.

This affects macros as well

macro_rules! foo(() => ([3]))
foo().to_owned()

Untitled.rs:3:10: 3:11 error: unexpected token: `.`
Untitled.rs:3     foo!().to_owned()
                        ^

Looks like a dup of #5941. (foo!()).to_owned() should work.
