Subject: Re: inject idiom

Thanks to both of you ara.t.howard and Kentaro-san for the nice hints. 
As far as I could tell from your tips, Ruby-style encourages conciseness 
(hence the use of hash.update or the custom .set method that returns the 
hash). And it seems that inject({}) is in  any case preferred to h={} 
and each loop, right?

Yes. Short and to the point but still quite clear to a beginner.

I liked the map method a lot (it reminds me the Perl map) and the way 
one can build the hash step by step with .update (or .merge!) [on that, 
I checked in The Ruby Programming Language]. I'll try to stick on that 
kind of idiom.

I am already used to this with Perl... (I pasted a slightly less spaced 
code here)

I got your point on minimising method chaining but not what you meant 
with line #42.

Thanks again.

Kind regards, Ömer.
