Well, it would be NICE if you could do:

alias :builtin_backquote :`
def `(cmd)
  puts "hello"
end

... then ...

def `(cmd)
  builtin_backquote(cmd)
end

But, alas, it doesn't like :`, nor can you use '`'.intern (at least in 
1.6.8)

But, you CAN do something like this instead, and it works "fine" 
(depending on your definition of "fine" ;)

$builtin_backquote = method('`'.intern)
def `(cmd)
  puts 'hello'
end

`uptime`

def `(cmd)
  $builtin_backquote.call(cmd)
end

`uptime`

Somebody else is bound to offer a better solution than this, but it is a 
quick way to get it done. =)
