Overview

Forbids the ternary conditional. ? and : are punctuation that already mean other things in Ruby (valid?, :symbol), so the reader disambiguates characters before seeing the branch — and the ternary hides a branch inside an expression, where skimming misses it. Inside a hash or an argument list, extract a named local and branch on it.

Examples:

# bad
status = saved ? :applied : :failed

# good
if saved
  status = :applied
else
  status = :failed
end
