Subject: Re: named scope lambda string substitution problem

Hey Brian,
This is the syntax error I get. The code I posted is enough to trigger
it in a simple class. I modified and added line numbers below.


[user@silvia proj-git]$ ruby foo.rb
foo.rb:8: syntax error, unexpected kDO_BLOCK, expecting '}'
    bar.each do |b|
               ^


1  class Foo
2  named_scope :foo, lambda {|foo, bar|
3     foo.each do |d|
4       foo = "this line doesn't work #{s}"
5       baz = "something like this works " + s
6     end
7
8     bar.each do |b|
9     end
10 {
11  :conditions => {'baz' => 1}
12
13 }}
14 end
