Subject: Re: dynamically calling methods that require a block

Ah, right I forgot the ampersand.  I needed to be able to define the 
block separately from the send call, so I tried this:

cond = Proc.new {|x| x > 2}
a.send(:detect, cond)

but I needed that second line to be
a.send(:detect, &cond)

thanks!
