This can be a good thing though as there are many situations where undisiciplined(bad) code does not matter and the development speed does ... Discipline often takes more time and patience which is why it is frequently skipped with an evil laugh

Yes, but are these trade offs always necessary? Can we write good code quickly? Can we design languages that makes the "right" choice easier without impacting flexibility?

Fools will write bad code in any language. Geniuses will write wonderful code in any language. However in the middle ground there are a lot of reasonable people trying their best to do a decent job - and I want my programming language to help as much as possible.

I think it's harder to write bad code in Perl 6 and Ruby because they naturally support some features that you have to jump through hoops to get in Perl 5.
