Yes, defintely do watch out for that BLS.

STL containers act like value types.

std::vector<int> a,b;
...// put some stuff in vector a
b = a;  // now b has a copy of every element of a
a[4] = 9;  //b[4] unchanged


In D currently to get that behavior have to do .dup:
int[] a,b;
b = a.dup;

So my STL-like interfaces have D-ish dup functions to make value copies.

But BLS, you should watch out for any such assignments of STL containers 
in your code, and change them to a = b.dup type things.
