# The build cache is required to build anything. It also may be needed to
# initialize the build system, which is needed for commands like 'go env'.
# However, there are lots of commands the cache is not needed for, and we
# shouldn't require it when it won't be used.
#
# TODO(golang.org/issue/39882): commands below should work, too.
# * go clean -modcache
# * go env
# * go fix
# * go fmt
# * go generate
# * go get -d
# * go list (without -export or -compiled)
