Lo que suele suponerse

a flag with NoOptDefVal set binds a subsequent space-separated argument as its value during command-line parsing

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

Contrato

• fs.Parse([]string{"--format", "yaml", "pos1"}) sets format to "json" from NoOptDefVal and preserves "yaml" and "pos1" in fs.Args()
• fs.Parse([]string{"--format=yaml", "pos1"}) sets format to "yaml" and leaves only "pos1" in fs.Args()
• fs.Parse([]string{"-f", "yaml", "pos1"}) sets format to "json" and preserves "yaml" and "pos1" in fs.Args()
• fs.Parse([]string{"-f=yaml", "pos1"}) sets format to "yaml" and leaves only "pos1" in fs.Args()
• fs.Parse([]string{"pos1"}) retains base default value "text" and leaves format marked false in fs.Changed()
• fs.Parse([]string{"--format"}) sets format to "json" and marks format as true in fs.Changed()
