When playing around with generics, I ran into what I perceive as an odd limitation.
I forked an audio package "beep" to do some fun generics with it. https://github.com/kardianos/beep/blob/master/interface.go I was trying to use the following interfaces: type Point[S Size] interface { // NOTE: Uncommenting the next line will result in errors. // [1]S | [2]S [2]S } type Size interface { float64 | float32 } I was thinking I could change the internal data structure from float64 or float32. This part works. I was thinking I could change the internal data structure from one channel to two with [1]S | [2]S. Now I realize this probably isn't a great idea to begin with, but hear me out... When I try to change to a union between len 1 array to len 2 array: 1. I cannot compile any access to point[1] even if behind a len(point) guard. 2. "for range point" appears to stop working at all, though I feel like it should still work, as it would work on either data type. I fully get why this is probably not a good serious approach, but more then anything, could someone help me with the why of the compiler errors? The specific error is "(P has no core type)".
