Subject: defined? var in a var name

hi, all.

I'm create a environment.rb in cucumber which stores a lot of env descripts.
like:
$host = "10.10.101.1"
$user =" root"
$password = "123"

while some one remove something, it might cause our automation stop.
so i add 1 var checker, like
vars = ["$host", "$user", "$password"]
def check_var(var)
  raise "#{var} not defined" if !defined?(var)
end
vars.each do |var|
  check_var(var)
end

but defined?(var) always return local-var.

i tried eval %Q{defined?("#{var}")}
still, returens "expression"
