--- Comment #1 from Denis Shelomovskij <verylonglogin.reg@gmail.com> ---
Another testcase:
---
enum E { a }

auto f(inout(E) val) { return val; }
---
main.d(3): Error: variable main.f.val inout variables can only be declared
inside inout functions
main.d(3): Error: inout on return means inout must be on a parameter as well
for inout(E)(inout(E) val)
