  • 85 lines for haskell vs 1105 Lines ( C++) ( 10hours vs non ddliv (others: ada: 800 LOC / 30 h )). ( A Student in haskell : 156 Lines /8 h )
  • the examiners did not believe (Dr Level )it was an executable program, but some kind of High level specs (p14). ,or says « too cute ( for its own good) »
  • P11, 5(10) : a newly hired college graduate, who was then given 8 days to learn Haskell. … After this training period, the new hire was handed the geo-server specification and asked to write a prototype in Haskell. … 156 LOC / 8 hours
  • P14 : the examiners were surprised and suspicious when told this a real executable program and based on preconception of their past experiences, thought it was a mixture of requirement and top level design.
Wiger, U., & Ab, E. T. (2001). Four-fold Increase in Productivity and Quality-Industrial-Strength Functional Programming in Telecom-Class Products.

P24(28). 7 . Some concrete comparisons of source code volume have been made, as applications written in C++ have been rewritten in Erlang, resulting in a ten-fold reduction in the number of lines of uncommented source code. Other comparisons have indicated a four- fold reduction. A reasonable conclusion is that productivity increases by the same factor, given the same line/hour programmer productivity. When measuring product quality in number of reported errors per 1000 lines of source code, the same relationship seems to exist: similar error density, but given the difference in code volume, roughly 4-10 times fewer errors in Erlang-based products.
