           Summary: [REG2.097] Error: mismatched function return type

test.d(3): Error: mismatched function return type inference of `void` and
`noreturn`

The return type of bun should be void, as in fun's.

If the gun and fun calls are swapped, the error message changes:

test.d(3): Error: cannot return non-void from `void` function

But, "returning" a "noreturn" value should be allowed from a void function.

Worked in 2.096.0.
