I suggest to extend std.array.empty to work with associative arrays too:


import std.array;
void main() {
    int[] a;
    assert(a.empty); // OK
    int[int] aa;
    assert(aa.empty); // Error
}


DMD 2.054:
test.d(6): Error: template std.array.empty(T) does not match any function
template declaration
test.d(6): Error: template std.array.empty(T) cannot deduce template function
from argument types !()(int[int])
