This is neat. Very Ruby, imho.

this looks like what I did... it also looks like the above... see:

def Fp2 (file, skip, &procarg)
	File.open(file) do |f|
	    skip.times {f.readline}
		f.each {|line| procarg.call(line)}
	end
end

Anyway, it looks "dirty" maybe because of &/call... I need more practice :-)
