There are multiple issues with the code you've written. First of all you cannot
have a main function with betterC because dmd creates a d_run_main function
which is the entrypoint of d programs. Typically, you just create the object
file with betterC and then you link it with some C code. This is a minor
aspect, regarding the test code.

The main issue with the code is that the delegate (() => i) requires a closure
that is allocated with the GC. Since you are compiling with -betterC, the GC is
not available.
