/**
* The syntax for binary names that appears in a class file, as defined in the <a
* href="https://docs.oracle.com/javase/specs/jvms/se7/html/jvms-4.html#jvms-4.2">JVM Specification,
* section 4.2</a>. A {@linkplain BinaryName binary name} is conceptually the name for the class or
* interface in a compiled binary, but the actual representation of that name in its class file is
* slightly different.
*
* <p>Internal form is the same as the binary name, but with periods ({@code .}) replaced by forward
* slashes ({@code /}).
*
* <p>Programmers more often use the binary name, leaving the internal form as a JVM implementation
* detail.
