Quoting Go Code Review Comments:

    The import . form can be useful in tests that, due to circular
    dependencies, cannot be made part of the package being tested:

        package foo_test

        import (
            "bar/testutil" // also imports "foo"
            . "foo"
        )

    In this case, the test file cannot be in package foo because it
    uses bar/testutil, which imports foo. So we use the 'import .'
    form to let the file pretend to be part of package foo even though
    it is not. Except for this one case, do not use import . in your
    programs. It makes the programs much harder to read because it is
    unclear whether a name like Quux is a top-level identifier in the
    current package or in an imported package.`,

composability.

Quoting Go Code Review Comments:

    Error strings should not be capitalized (unless beginning with
    proper nouns or acronyms) or end with punctuation, since they are
    usually printed following other context. That is, use
    fmt.Errorf("something bad") not fmt.Errorf("Something bad"), so
    that log.Printf("Reading %s: %v", filename, err) formats without a
    spurious capital letter mid-message.`,

		Title: `Poorly chosen receiver name`,
		Text: `Quoting Go Code Review Comments:

    The name of a method's receiver should be a reflection of its
    identity; often a one or two letter abbreviation of its type
    suffices (such as "c" or "cl" for "Client"). Don't use generic
    names such as "me", "this" or "self", identifiers typical of
    object-oriented languages that place more emphasis on methods as
    opposed to functions. The name need not be as descriptive as that
    of a method argument, as its role is obvious and serves no
    documentary purpose. It can be very short as it will appear on
    almost every line of every method of the type; familiarity admits
    brevity. Be consistent, too: if you call the receiver "c" in one
    method, don't call it "cl" in another.`,
