the code:

import std.container;
void main(){
    auto t = make!(RedBlackTree!(string));
    t.insert(["1","2","3"]);
    t.removeKey("1");
}


the fireworks:

error9.d(10): Error: template
std.container.RedBlackTree!(string).RedBlackTree.removeKey(U) if
(isImplicitlyConvertible!(U,Elem)) does not match any function template
declaration
error9.d(10): Error: template
std.container.RedBlackTree!(string).RedBlackTree.removeKey(U) if
(isImplicitlyConvertible!(U,Elem)) cannot deduce template function from
argument types !()(string)

t.removeKey!string("1");

I believe that this is a case of template inferrence failing, because it's deciding that the input to removeKey is a range a dchars rather than a single string, and you can't covert dchar to the element type of the container (string), and so compilation fails. I don't know how fixable it is with template constraints. Hopefully someone can sort it out, but it may be that the compiler is just too stupid in this case.
