Things that look like accidental violations of variable scoping,
until the language has something a bit more elegant to handle said
scoping:

  i = 3
  ...
  arr.each { |i| do_something_with(i) }
  ...
  print "Why is i not 3?\n"

if the project is such that it's not worth implementing unit
tests (aka, it's a quick hack), the more static analysis you
can get, the better.  Plus, it's always nice to have redundancy
in your sanity checking.
