Variables that begin with capital letters are constants in Ruby. Probably
`Name` shouldn't be a constant. Methods aren't constants, so their names are
all lowercase, so `Puts` should actually be `puts`. A slight
reinterpretation of this program:

name = gets
puts "Hello, #{name}"



If it makes you feel more comfortable being explicit, this translates
(approximately) to:

name = $stdin.gets()
$stdout.puts("Hello, #{name}")
