A number of little updates have been applied to the Copper interpreter and documentation this week including better type identification and string-related methods.

New changes this week in Copper fill in some of the gaps that show up when trying to use Copper for real-world projects. The first of these is the indication of the support of multiple interfaces, which solves the dilemma of distinguishing between polymorphic objects turned into Copper objects. The second is the addition of a system function that enables the sharing of user-created function bodies.
In other notes, the string_map extension received a bug fix for not correctly returning when “exit” was called in the middle of the callback function it was given.
I did some speed profiling… – something I probably should have done a before outright stating my virtual machine is “not improvable” on its blog. Of course, I know better, and that’s why I performed speed profiling.
The profiling narrowed down the bulk of the speed bottleneck to function calls (actually, it was a confirmed educated guess, but I think I know where the other bottlenecks are).
Not to the surprise of any expert, the primary issue turned out to be string comparison. Strings add up to be amazingly expensive. Currently, there are too many function calls that depend on them in the script execution section of the engine.
