I suppose the linker optimized the functions away since they

AFAIK assert(0) and other falsey assert have a special meaning
for compiler.
So probably it's not so hacky but just a way to say that case
can't happen.
It is used also for:
auto myfunc(int i)
{
if (i == 0) return 10;
else if (i == 1) return 3;
assert(0);
}
And also with non final switch using
switch(var)
{
case ...
...
default: assert(0);
}
I'm good with the assert(0), I'm not so happy with the linker not
being able to create a binary without the -ffunction-sections
option.
I think there needs to be a ctimport keyword or something. I
should not have to deal with the imports only used during compile
time. it is not a good thing.
