Therefor the initializer must be constant.

cat > bug.d << CODE
immutable char[5] foo = "abcde";

int bar(string a, string b)
{
    return 0;
}

void baz()
{
    enum s = bar(foo, foo[0 .. $]);
}

// Assertion failed: (!v->isDataseg() || v->isCTFE()), function push, file
interpret.c, line 108.
version (none)
enum s = bar(foo, foo[0 .. $]);
CODE

dmd -c bug

Sorry, you're point was obviously that __dollar should be resolvable
at compile time.
