The problem is that different programs need different things for slice equality. Some want pointer equality as you suggest. Some want element comparisons, as is done for array equality. Without an obvious semantics for the operation, the language omits it entirely. To store slices in maps using pointer equality, you could perhaps store a pointer to the slice instead.
