Reading the code passed inside a block?

ruby-talk

Is it possible to read the code passed in a block, as, say, a String?
Or in any other way? That is, if I make a method call like:

reflector.superReflectiveMethod { |i| i >= 5 }

is there any way I could get output like

You passed in this code: “i >= 5”

Thanks in advance,

Francis

But if you are prepared to “cheat” and do something on the calling side,
I’ve used this explicit trick:
