As a special case, if the package list is a list of .go files from a
single directory, the command is applied to a single synthesized
package made up of exactly those files, ignoring any build constraints
in those files and ignoring any other files in the directory.

Directory and file names that begin with "." or "_" are ignored

	// If exact is set, types unify if they are identical (or can be
	// made identical with suitable arguments for type parameters).
	// Otherwise, a named type and a type literal unify if their
	// underlying types unify, channel directions are ignored, and

	ignoreTags     bool // if set, identical ignores struct tags
	ignoreInvalids bool // if set, identical treats an invalid type as identical to any type
}

The following flags are also recognized by 'go test' and can be used to
profile the tests during execution:

	-benchmem
	    Print memory allocation statistics for benchmarks.
	    Allocations made in C or using C.malloc are not counted.

	-blockprofile block.out
	    Write a goroutine blocking profile to the specified file
	    when all tests are complete.
	    Writes test binary as -c would.

are dependencies on libraries beyond libc, external linking is likely
to work better. The compilation of a package records the relevant
information to support both linking modes, leaving the decision
to be made when linking the final binary.

Linking Directives

In either linking mode, package-specific directives must be passed
through to cmd/link. These are communicated by writing //go: directives in a

			// otherwise erroneous — for example, perhaps the author forgot to 'git
			// add' their updated go.mod file after adding a new package import, or
			// perhaps they made an edit to the go.mod file using a third-party tool
			// ('git merge'?) that doesn't maintain consistency for module
			// dependencies. If that happens, ideally we want to detect the missing
