just curious, according to power law 
(http://en.wikipedia.org/wiki/Power_law) there should be 20% of language 
constructs (structural patterns) that are used 80% of time.

It would be interesting to process with flay let's say about hundred of 
most popular gems and collect pattern usage statistics.
To answer the question - what of the ruby constructs and structural 
patterns are used most often?

And then we can apply these statistical knowledge to shape the API of 
the ruby itself, to make these most used constructs and patterns more 
simple and compact.

I created very basic tool that demonstrates how the power law applied to 
the size of sources, 
http://ruby-lang.info/blog/code-statistics-and-the-power-law-paretto-80-20-rul-hqo

Whould be interesting to see how it's applied to the syntaxis and the 
structure of the ruby code.

P.S. Actually 20% is too wide, we don't need them all. But because the 
Power law has the property of self-similarity, in these most used 20 
percents there alre also 20 most used percents (and so on).
And these 4% (20% of 20%) are covering 64% (80% of 80%) of all patterns 
used in code.
