Impossible Go!
summary
A sequence of concrete Go surprises: a slice shares memory with its array until an append crosses slice reallocation after capacity exceeded and silently copies; struct equality compares fields but ignores blank struct fields ignored in comparison; maps iterate in randomized order so iteration order is not a valid contract; slices, maps and funcs are not comparable with ==; functional options use variadic functions returning functions to set defaults; custom UnmarshalJSON chooses concrete types for interface fields; eight CPU-bound goroutines can deadlock the program on an 8-core machine.
