Parallel Implementations « #AltDevBlogADay: "It is completely reasonable to violate some generally good coding rules while building an experimental implementation – copy, paste, and find-replace rename is actually a good way to start. Code fearlessly on the copy, while the original remains fully functional and unmolested. It is often tempting to shortcut this by passing in some kind of option flag to existing code, rather than enabling a full parallel implementation. It is a grey area, but I have been tending to find the extra path complexity with the flag approach often leads to messing up both versions as you work, and you usually compromise both implementations to some degree."
