Hi Jeff,

Another interesting question is, what is standard way of writing one
liner code and multiliner

I read somewhere like oneliner should be written using {}
and do ... end for multiliner

For example:

one liner:

data = Hash.new { |h,k| h[k] = [] }

and multiliner:

prs.each do |line|
    (pr, pr_scope, state) = line.split(/,/)
    data[pr] << Hash[state, pr_scope]
end
