Just for clarification: 1D arrays (i.e., Vectors) in Julia are already growable in the same way as your growable arrays--the backing array doubles in size when it grows beyond its limit. But you cannot do the same thing for 2D (or greater) arrays. A couple of ways around the current limitation:

Re: [julia-users] Re: MongoDB and Julia

There is no such function right now. In Julia, the common paradigm for manipulating code is to manipulate the expression itself. You can, of course, output the expression, and it often looks better than what David posted above (e.g., this is what parse outputs). Perhaps you can discuss a
