A "const" or "immutable" declaration would declare a constant

when doing metaprogramming. Constant/immutable declarations
make sense for values that will be used in multiple places by
code at runtime.
I'm with Mike - thanks Vlad, that makes it perfectly clear. I
just wonder slightly why a language that prides itself so on its
metaprogramming capabilities does not have a keyword that makes
it obvious
Think of an abbreviation for compile-time-constant.
But yes, thanks.
BTW, why does an immutable integer type need to have an address?
