--- Comment #5 from Walter Bright <[email protected]> --- The key to understanding perplexing examples is to ruthlessly rewrite them in terms of `int*` and plain functions. Get rid of slices, this references, structs, member functions, etc. which do nothing but obfuscate what is happening, as they are just fancier versions of int* and functions. --
