Hi All,

Recently I found a slightly annoying behavior in Ruby -- local variable
scoping: Example of code:

Javascript version:

var aNumber = 3
function doSomething()
{
   var anotherNumber = aNumber *2
}

Translate to Ruby:

aNumber = 3
def doSomething
    anotherNumber = aNumber * 2
end

aNumber goes somewhere in the meta-class of Object, I think.

Here's a useful idiom:

  @aNumber=3
      ==>3
  def doSomething; @aNumber*2; end
      ==>nil
  doSomething
      ==>6

You could redo your example appending "@" before evaling the variable, I suspect.
