Suppose you wanted to create a 2-dimensional list. This can be easily done with the list constructor. ex:
mylist = list(list(9))
Now suppose we wanted to access the item in the second dimension of the list. Lists are special in that they are objects that contain other objects without themselves containing variables. To access an item in the list, we use the item_at() system function. This returns an object. Performing it once will return the child list. From there, we can call item_at() in succession to access the item of interest:
myitem = item_at(item_at(mylist: 0) 0)

Under the hood, Copper is a rather complicated system. It has to be that way in order to ensure Copper is safe (no null pointer errors) within Copper code. However, on the C++ side, this makes it tricky to just access the members and data of a FunctionObject, the most important of all Copper objects. Now there’s an easy way.

My language link was posted on ycombinator news yesterday (?), resulting in a spike in the views on this site. I read through the comments and a couple things stood out.

After deliberating over the matter, I’ve decided that it’d be best to write an extension for Copper that would enable file reading and writing. This would enable the language to finally be general purpose, putting it among the big boys like Python. While the current Copper VM is certainly not fast enough to compete, the ease, power, and syntax of the language make it a highly tempting alternative.
