Subject: Applying an operator to a list

Hello all, I have a quick question:
Is it possible to create a Lisp style apply function with Ruby, and
would I have to use eval to create one? The function would work as
follows:

[1, 2, 3].apply('+'.intern) # => 6
[2, 3, 4].apply('*'.intern) # => 24

I know I could easily sum a list like so:

[1, 2, 3].inject(0) {|n, value| n + value}

So, I guess this is just a curiosity question.
