I see. I got confused by a source being commited into the Hg and considered 
that an attempt to write CLI parser from scratch.

SendOpts API[2] benefit could be its modularity support - e.g. various modules 
contribute its options and the system then verifies overall consistency of a 
command line and distributes the CLI arguments to appropriate modules. If such 
composition and decomposition is not needed then [1] looks OK and in certain 
areas (number format of an argument, for example) more powerful.
