auto some_array = new string[][](x, y);

Note, this creates 10 arrays of 10 elements all on the heap, and then a 
10 element array to point at them.

If you wanted an array of 10 *fixed sized* arrays (which is what your 
code was trying to do), then you need to have the first dimension be a 
compile-time constant such as a literal or an enum/immutable.
