The specification states that:

The __FILE__ and __LINE__ expand to the source file name and line number at the
point of instantiation.

This is not the case for the code below:

-------------------
import std.stdio;

void ODSfd(alias n)() {
      writefln("%s:%s | %s = %d", __FILE__, __LINE__, n.stringof, n);
}
void ODSfs(alias n)() {
      writefln("%s:%s | %s = %s", __FILE__, __LINE__, n.stringof, n);
}
void ODSfx(alias n)() {
      writefln("%s:%s | %s = 0x%08x", __FILE__, __LINE__, n.stringof, n);
}

void main() {
   int zbar = 5;
   string foo = "hi";

   ODSfd!(zbar);
   ODSfs!(foo);
   ODSfx!(zbar);
}
-------------------

Expected output:
file.d:17 | zbar = 5
file.d:18 | foo = hi
file.d:19 | zbar = 0x00000005


Actual output:
file.d:4 | zbar = 5
file.d:7 | foo = hi
file.d:10 | zbar = 0x00000005

Note that the docs say that referring to template value parameters. The code
you posted is intended behavior; you would have to add a couple value
parameters to each one that default to __FILE__ and __LINE__ and print those
out.

In that case, the below has the same result.

------------
import std.stdio;

void ODSfd(alias n, string file = __FILE__, int line = __LINE__)() {
      writefln("%s:%s | %s = %d", file, line, n.stringof, n);
}
void ODSfs(alias n, string file = __FILE__, int line = __LINE__)() {
      writefln("%s:%s | %s = %s", file, line, n.stringof, n);
}
void ODSfx(alias n, string file = __FILE__, int line = __LINE__)() {
      writefln("%s:%s | %s = 0x%08x", file, line, n.stringof, n);
}

void main() {
   int zbar = 5;
   string foo = "hi";

   ODSfd!(zbar);
   ODSfs!(foo);
   ODSfx!(zbar);
}
-----------------

Expected Output:
linefile.d:17 | zbar = 5
linefile.d:18 | foo = hi
linefile.d:19 | zbar = 0x00000005

Actual Output:
linefile.d:3 | zbar = 5
linefile.d:6 | foo = hi
linefile.d:9 | zbar = 0x00000005

This only happens with explicit instantiations foo!(targs)(args).
In that case semantic is run in a different scope.
A workaround for functions is to split the parameters into explicit
and default parameters.

template foo(T)
{
    void foo(size_t line = __LINE__)()
    {
        pragma(msg, line);
    }
}

Oh, I thought this one was already fixed.
Now it is, thanks a lot Kenji.
