Aside questions of personal style & taste, _I_ could not hold such long funcs. Far too much to manage for my head, about unmaintainable for me.

My common limit is about one editor screen (~ 35 lines), comments included, which reveals not only practicle, but also about what my head is able to cope with at once. And my programming style rather leans toward clarity (--> low code density), meaning that 1 line of a "smart" coder may map to 2 or 3 of mine. An absolute limit would be about 2 screens.

To sum up:
  150 lines by luke
  * 2 (density)
  * 2 (comments)
= 600 lines by myself

... compared to my ~ 50 lines medium limit means Luke is a ~ 12 times smarter coder than I am! ;-)
This is a new evidence that coding efficiency is more a question of coder quality than anything else...
