If you need to take the address of a constant, use immutable or const (doesn't really matter, but I prefer immutable). If you don't need the address, use enum.

Why not static immutable?

For global scope? static has no effect there as far as I know. Looking at the ASM output on run.dlang.io, I see no difference between the two:

static immutable foo = 10;
immutable bar = 20;

LAT     group   
;File = onlineapp.d
        public  immutable(int) onlineapp.foo
        public  immutable(int) onlineapp.bar

...
                mov     EDI,0Ah
call @safe void std.stdio.writeln!(immutable(int)).writeln(immutable(int))@PLT32
                mov     EDI,014h
call @safe void std.stdio.writeln!(immutable(int)).writeln(immutable(int))@PLT32
