Test case 1:

string foo()
{
     string s = "ab";
     return s[0 .. $];
}

template T2(string s)
{
}

template T1()
{
     enum s = foo();
     alias T2!(s) t2;
}

int bar()
{
     alias T1!() t1;
     return 0;
}

int baz(int x)
{
     return 0;
}

static assert(baz(bar()) == 0);

void main()
{
}

Error: expression "ab"[0u..2u] is not a valid template value
argument

Test case 2:

string bar()
{
    string s = "ab";
    return s[0..$];
}

template T1()
{
    enum T1 = bar()[0..$]; // error
}

string baz()
{
    return T1!();
}

string foo(string s)
{
    return s;
}

static assert(foo(baz()) == "ab");

void main()
{
}

Error: variable __dollar cannot be read at compile time
