The following does not compile:

auto tree = RedBlackTree!string("foo", "bar", "baz");

Error message:

Error: template std.container.RedBlackTree!(string).RedBlackTree.__ctor(U) if
(isImplicitlyConvertible!(U,Elem)) does not match any function template
declaration
Error: template std.container.RedBlackTree!(string).RedBlackTree.__ctor(U) if
(isImplicitlyConvertible!(U,Elem)) cannot deduce template function from
argument types !()(string,string,string)

It is an issue with type inference from typesafe variadics, the constructor for
RedBlackTree deduces U to immutable(char) rather than string:

this(U)(U[] elems...) if (isImplicitlyConvertible!(U, Elem))

auto tree = redBlackTree!string("foo", "bar", "baz");

compiles with dmd 2.059
