this is what I need, I guess I has to wait.
my question is how to easy use struct static initializer

Fake code:

I plan to use function pointer least significant bit to store
some information.
If there is no GC on my system, I think it will help the memory
is well aligned.
The question is all the function least significant bit is zero ?

You can't append to an array in betterC code, because making
space for the new elements requires allocating memory, and that
uses the GC.
In theory, since you're only using the GC during CTFE, it
shouldn't be a problem, but

thanks for reply, minimal perfect hashing seems good for this

The use case is translate http header key into enum.
this is the current code : https://run.dlang.io/is/lpw29w
In this fake code I only list a few headers, it should be more.
but less then 128 and only include the a few codes.
