It's already in the list [1], it's been there for two years. 
Unfortunately it's not that simple. The current implementation is 
a very simple mapping of a name to an import. What if there are 
multiple module level symbols with the same name in Phobos or 
druntime? Then the compiler will be wrong in some of those cases. 
Also, take this for example:

auto too(T, U)(U value)
{
     return value;
}

void main()
{
     auto a = 3.to!string;
}

This will result in a compile error:

Error: no property `to` for type `int`, perhaps `import 
std.conv;` is needed?

Obviously I meant to call the function `too` in the same module. 
Not `std.conv.to`.
