For some brain glitch reason, I was sure I was posting to 
bugzilla. Sorry for that.


Why not configure this group so that it refuses direct posts or 
issues warnings?

Another test case. The error is different but the root cause must 
be the same.


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

Reduced test case:

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
