Not exactly. If they're global or static, then they both have to be known at
compile time (though you can initialize an immutable global or static in a
static constructor, which you can't do with an enum). The primary difference is
that an immutable variable is actually a variable with a location in memory,
where an enum is just a value that gets copy-pasted wherever it's used and is
not associated with any particular location in memory. So, which you use tends
to depend on whether you need it to be associated with a particular address in
memory and whether you want its value to be copied everywhere.
