this is an obvious case of battling the type system that just gets in the way. The "before" version obviously sucks, but the "after" with magic sprinkled in - sucks even more! is there an alternative solution?
I dont understand what's going on but it looks like a hack to avoid code duplication. We should be OK with duplication sometimes because it's more explicit and straightforward to mingle and debug.
>In Pcodec I now have 9 data types and 47 matches
So 9 * 47 - 47 = 376 lines the author got rid of ? Which would imply that if he adds a tenth datatype, he doesn't have to update 47 match blocks sprinkled over the whole code base ?
