# blocklist_imports is a simple check against unwanted packages. The following
# packages are banned:
#
# * Packages errors and log are replaced by our own packages in the
# github.com/AdguardTeam/golibs module.
#
# * Package io/ioutil is soft-deprecated.
#
# * Package reflect is often an overkill, and for deep comparisons there are
# much better functions in module github.com/google/go-cmp. Which is
# already our indirect dependency and which may or may not enter the stdlib
# at some point.
#
# See https://github.com/golang/go/issues/45200.
#
# * Package sort is replaced by golang.org/x/exp/slices.
#
# * Package unsafe is… unsafe.
#
# * Package golang.org/x/net/context has been moved into stdlib.
