If you need to take the address of a constant, use immutable

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
If I'm right on classes/structs static immutable != immutable. So
if you need to replace enum in those cases too, static immutable
works fine everywhere. Right?
