--- code
struct MyString
{
    private string value;
    mixin Proxy!value;
    this(string s){ value = s; }
}

// Test BUG #
MyString a = MyString("a");
MyString b = MyString("b");
MyString a1 = MyString("a");
assert(a == a);
assert(a == a1);
assert(a != b);
---

--- compile
$ dmd testproxy.d
../src/phobos/std/typecons.d(2658): Error: undefined identifier 'startsWith'
testproxy.d(16): Error: template instance
testproxy.main.MyString.Proxy!(value).opEquals!(MyString) error instantiating
---

If the test code placed in typecons.d, it's ok.
If place it in another file, compiles error. Bug if add 'import std.algorithm',
compiles passed, why it depends user's context?

Seems it is a DMD's bug?
