Subject: [ruby-core:72049] [Ruby trunk - Bug #11803] NoMethodError when	calling String#gsub

Issue #11803 has been updated by Hans Mackowiak.


first i dont think its a good idea in a to_s method to change the value of the object.
otherwise you need to use @instance variables then it works:

~~~ruby
class TestFail
  def initialize(word)
    @word = word
  end

  def to_s
    return unless @word
    @word.gsub(/a/, "")
  end

  def word
    @word
  end
end
~~~

Bug #11803: NoMethodError when calling String#gsub

----------------------------------------
Assigning the result of a call to String#gsub throws a NoMethodError. It seems to have to do with assigning the return value to a variable with the same name as the method returning the string gsub is called on. I've included short script which reproduces the issue.
