=== a.d ===
import std_algorithm;
=== b.d ===
import std_algorithm;

void f()
{
    startsWith("", "");
}
=== std_algorithm.d ===
dchar front(A)(A) { }

uint startsWith()() { }

bool startsWith(R1, R2)(R1 doesThisStart, R2)
if (is(typeof(doesThisStart.front)))
{
    return true;
}
=== compiler command line ===
dmd -o- a.d b.d
=== compiler output ===
b.d(5): Error: template std_algorithm.startsWith does not match any function
template declaration
b.d(5): Error: template std_algorithm.startsWith cannot deduce template
function from argument types !()(string,string)

Changing the order of files on the command line unbreaks compilation.
