string's empty is actually a function in std.array or std.range

the call can't match even when the alias this is tried.
Add the following, which brings std's empty into the overload
set, and it works:
static import std.range;
alias empty = std.range.empty;
----test.d
static import std.range;
alias empty=std.range.empty;
struct A{
string b;
alias b this;
}
struct MyRange{
}
char front(MyRange);
void popFront(ref MyRange);
bool empty(MyRange);
void test(A a){
a.empty;
}

$ dmd -o- test
test.d(16): Error: overload alias 'empty' is not a variable

No idea what dmd is doing.
However it works with
----
private auto empty(string s){
static import std.range;
return std.range.empty(s);
}
