Subject: [ruby-talk:20228] ruby accessing variables it doesn't need to?


Why does this:

module Kernel
  def getschop!
    a.chop if a = gets
  end
end

while line = getschop!
  puts "#{line}!"
end

give:
../junk.rb:5:in `getschop!': undefined local variable or method `a'
for #<Object:0x8109c88> (NameError)

This works:

module Kernel
  def getschop!
    a = gets
    a.chop if a
  end
end


thanks,
