This program, dist, is the bootstrapping tool for the Go distribution.

As of Go 1.5, dist and other parts of the compiler toolchain are written
in Go, making bootstrapping a little more involved than in the past.
The approach is to build the current release of Go with an earlier one.

The process to install Go 1.x, for x ≥ 22, is:

1. Build cmd/dist with Go 1.20.6.
2. Using dist, build Go 1.x compiler toolchain with Go 1.20.6.

env TESTGO_VERSION=go1.21.0
env TESTGO_VERSION_SWITCH=switch

# If the main module's go.mod file lists a version lower than the version
# required by its dependencies, the commands that fetch and diagnose the module
# graph (such as 'go mod graph' and 'go mod verify') should fail explicitly:
# they can't interpret the graph themselves, and they aren't allowed to update
# the go.mod file to record a specific, stable toolchain version that can.

! go mod verify

(package-scope instrumentation is enabled via "-pkgcfg" option).

When generated instrumented code, the cover tool computes approximate
basic block information by studying the source. It is thus more
portable than binary-rewriting coverage tools, but also a little less
capable. For instance, it does not probe inside && and || expressions,
and can be mildly confused by single statements with multiple function
literals.

// This is more useful than having it default to generating objects for the

The new [ParseCookie] function parses a Cookie header value and
returns all the cookies which were set in it. Since the same cookie
name can appear multiple times the returned Values can contain
more than one value for a given key.

The new [ParseSetCookie] function parses a Set-Cookie header value and
