Subject: Re: Any way to get the calling method's binding?

In the meantime, you could do this:

def trace (expr)
    LOG.debug "#{expr} = #{yield expr}"
end

def something
    x=5
    x=7
    trace "x+y", {|n| eval n}
end

something => 12

I'll admit that it'd be nice if the block passing could be automated; 
not sure how to do that off the top of my head.  This reminds me of 
dynamic scoping; anybody got any clue about how to do away with the 
block?  Maybe there's a way to do this with an extension?
