to be fair I didn't check it in D code as I was focusing on 
getting a new release of the Intellij plugin pushed to resolve 
the problem.

The 1.28.3 release will be fix the issue and be available shortly.

The way the plugin currently works it expected 
`/usr/include/dmd/phobos/std/experimental/checkedint.d` to exist 
on my system. It's not an ideal situation and certainly needs 
reworking but that's the way it is for now.

It's good that dmd can still compile if `import 
std.experimental.checkedint;` is used.
