Example:
In package io the type ByteReader defines an interface that wraps the method ReadByte() (c byte, err error).
What is the easiest way to find out which types in the standard library (i.e. listed here in golang.org/pkg) satisfy this interface?
Is this just a matter of experience or is there any other help?

When you define a new interface, you are defining a new reference data type. You can use interface names anywhere you can use any other data type name. If you define a reference variable whose type is an interface, any object you assign to it must be an instance of a class that implements the interface.
Mostly by experience. Anyway, for example:
jnml@fsc-r630:~/go/src/pkg$ egrep -nr '^func (.*) ReadByte\(' *
bufio/bufio.go:165:func (b *Reader) ReadByte() (c byte, err error) {
bytes/reader.go:59:func (r *Reader) ReadByte() (b byte, err error) {
bytes/buffer.go:289:func (b *Buffer) ReadByte() (c byte, err error) {
encoding/xml/xml_test.go:234:func (d *downCaser) ReadByte() (c byte, err error) {
strings/reader.go:58:func (r *Reader) ReadByte() (b byte, err error) {
jnml@fsc-r630:~/go/src/pkg$
And also the golang.org site has a case sensitive search capability.
