sure - everything in :ducktype=>list AND what parseargs needs - quite true.
Not just parseargs, but any other methods that the method calls. In your case, it was simply p, but in some other case, I might be passing a parameter all around the system, in which case, who knows what it'll need. (Is that bad design? If so, that's precisely one of the things I want to flesh out as an extra restriction we need to place on ourselves because we're using Ruby.)

huh?
def method(*argv)
pa = parseargs(argv){
arg :x, :ducktype => File.new('methods.txt').readlines.each { |line|
line.chomp
}
}
p pa.x.upcase.downcase
end
we're all friends here so i assume people will offer up any criticisms come to
mind.
Ok. Thanks!

ah. true true. at least the docs could show the rhs of the '=>' sign which
would, in 99% of cases, but quite informative.
cheers.

Only if it's an Array literal being passed to parseargs.
