The new warning is:

warning("converting dynamic arrays to boolean is deprecated, instead use
array.ptr");

For normal D programmers the right way to tell if an array (and eventually
associative array) is empty is with the std.array.empty function, that tests
the length. You don't want future normal D programmers to start using .ptr
everywhere they want to test array emptiness.

So perhaps a better warning is:

"converting dynamic arrays to boolean is deprecated, instead use
std.array.empty"

On the other hand some programmers want really meant to use ".ptr". And some
programmers want to test "arr.length || arr.ptr" and so on.

So perhaps an alternative error message is:

"converting dynamic arrays to boolean is deprecated"
