Is there a solution that results the same static

Did you try looking at assembly generated by GDC or LDC with
full optimizations? For example GDC does quite better than DMD
for the proposed SafeInt type:

Also, see the table at the bottom of this comment:

Thanks for the pointers! My first priority a performant library,
secondary is a nice api, 3rd is a nice implementation. So that
kind of rules put Amy degradation compared to ints. I used DMD,
BTW.
I see no reason for the necessity of performance degradation.
Essentially I just want to assign a similar qualifyer like const
or immutable. They are checked and used at compile time, but
erased for runtime. Same here.
