Sure:

$ ruby -rubygems read_array.rb
Enter some numbers:
1
2
3

You entered:  [1, 2, 3]
$ cat read_array.rb
#!/usr/bin/env ruby -w

require "highline/import"

array = ask("Enter some numbers:", lambda { |n| Integer(n) rescue  
n }) do |q|
   q.gather = String.new
end
puts "You entered:  #{array.inspect}"

__END__

Hope that helps.
