Thanks for your thoughts. The above (my approach) fits so nicely with
the single table inheritance in Rails without implementing a single
line of code (except for the five lines above). With this, I get never
above the multiple of 500 (or was it 5000?) lines of code to get a
higher patrick.to_i value. But the #developer? (and alike) methods read
better, right.
