This functionality in this package is mostly captured in the Arena type.
Arenas allocate large chunks of memory for Go values, so they're likely to
be inefficient for allocating only small amounts of small Go values. They're
best used in bulk, on the order of MiB of memory allocated on each use.

Note that by allowing for this limited form of manual memory allocation

		q = q[len(q)-64:]
	}
	b := dangerousSlice(t)
	if len(b) > 256 {
		// Only worry about when we're near the end of a page.
		b = b[len(b)-256:]

		q[j-1] = 1 // difference is only found on the last byte
		for i := range b {

Use caution when passing '-u' to 'go get'. The '-u' flag updates
modules providing all transitively imported packages, not only
the module providing the target package.

Note that 'go mod vendor' only copies packages that are transitively
imported by packages in the current module. If a new package is needed,
