I want to append a 2D array to my 3D array. I expect it should be same

candidate ~= line;
writeln(candidate);
if (++counter > 1 ) break;

And I send the inputs below
201212?4 64
20121235 93
I expect a output like
[["201212?4", "64"], ["20121235", "93"]]
But instead I see
[["20121235", "93"], ["20121235", "93"]]
In short :
=~ replaces all the elements in the array with the last added. Where am
I doing wrong? How can I meet my expectation?
By the way I am posting the same question to stackoverflow at the same
time. Does sending questions to stackoverflow as well as here not
desirable for D community? If so I will just write here.
stackoverflow isn't normally looked at by those in the D community.
In your case its pretty simple. The buffer is being reused. So same
memory being added multiple times to the candidate.
Just slap on a .dup when adding it.
It'll duplicate the contents in new memory so it won't be assigned on
top of.
