Annoyed by polluted code and people not understanding what safe navigation operator is and using it everywhere.
If it is known that a variable can't be nil, suggest removing useless safe navigation calls.
# bad x = var.foo # <--- here, if var is nil, an error will be raised in any case var&.bar # <--- unnecessary safe navigation # good x = var.foo var.bar # bad if var var&.foo end # good if var var.foo end
