Subject: code optimpization: delete_if, each, send.



hi list,


i've a query string like inname:ruby,opt 

the query is splitted in [ 'in', 'name', 'ruby', 'opt']

where 'in' is the name of a function (in-> true|false)
that look inside an hash for a key 'name' and returns true 
if the value is 'ruby' || 'opt'.   


hashes are in an array called list.
i would delete from the list array who doesn't match 
the query.

-----------
  list.delete_if(){
    d = false
    tokens.each {|t|  # method, args, object
      if (! d)
        d = true if send(t[0].to_sym, t[1], t[2..-1])        
      end
    b
    }
  }
---------------

is there a better way?

tnx.
