def parse(*argv, into: nil)
argv = argv[0].dup if argv.size == 1 and Array === argv[0]
parse!(argv, into: into)
end
Parses command line arguments argv in order when environment variable POSIXLY_CORRECT is set, and in permutation mode otherwise. When optional into keyword argument is provided, the parsed option values are stored there via []= method (so it can be Hash, or OpenStruct, or other similar object).
