Those metrics don't amount to wisdom. Wisdom is something like realizing that you don't have to special-case some code over <here>, you just need to create a new reusable primitive over <there> that fixes two bugs with one stone, and you'd probably wind up needing it anyway. Both bits of code could sail through all the measurements of code maintainability you could come up with, and an agent suggest to me the brittle solution, but I came up with the more maintainable one.
