// A look into the future:
32
+
// When you allocate memory, you store the returned address in
33
+
// a const var. The pointer itself never changes — it always
34
+
// refers to the same allocation — but you can still read and
35
+
// write the data it points to.
36
+
//
37
+
// Example:
38
+
//
39
+
// const buf = try allocator.alloc(u8, 1024);
40
+
// buf[0] = 42; // fine: the *contents* are mutable
41
+
//
42
+
// Note:
43
+
// Passing this pointer to a function is cheap: it's just an address
44
+
// copied on the stack. The caller can work with the data without
45
+
// needing to know where it came from or how it was allocated.
