operator out of string

[kelt]

Hey,

I am a newbee in Ruby and since the language has many nice features it
struck me obvioous that it must be possible to evaluate a string in
such a way that it produces the corresponding operator. E.g.: "+"
would become a simple plus sign, thus allowing me to pass "+" as a
function to be done on two integers.

Thank you

kelt
