Thank you for the explanation.
I appreciate any helps.

 > (1..5).inject(:*) will return 120, or 5!

this is far beyond my reach at the moment, hahaha...
Ruby clearly have some unique features I haven't know yet.

By the way, the first time I had look at a ruby's syntax and
some progurams using Procs or lambdas(maybe), it reminded me
Curl language, which I used to use for a few years.

Do you know it?
I think Curl isn't and won't be famous as Ruby,
but it might be interesting for some Ruby programmers.
