Description
Hi,
Is there an option / way to ignore undeclared options and get them in a resultset so, I can handle them in a custom way?
Example scenario: Program A redirects unsupported arguments to another Program B called from inside program A.
Thanks.

Just rescue OptionParser::InvalidOption
.
As it can't tell if an unknown option has its argument or not, I didn't add such methods.
require 'optparse'
unknown = []
ARGV.options do |opt|
opt.on("--foo=FOO") {|v| @foo = v}
begin
opt.order! {|arg| unknown << arg}
rescue OptionParser::InvalidOption => e
unknown.concat(e.args)
redo
end
end
p unknown
p @foo
