The 'go test' command expects to find test, benchmark, and example functions
in the "*_test.go" files corresponding to the package under test.

A test function is one named TestXxx (where Xxx does not start with a
lower case letter) and should have the signature,

	func TestXxx(t *testing.T) { ... }

A benchmark function is one named BenchmarkXxx and should have the signature,

	func BenchmarkXxx(b *testing.B) { ... }

// they come up. A better solution is desired.
