If you check the method's senders, you will recognized
that it just provides a "nicer" error message for
SequenceableCollection>>#second, #third ... .
I suppose the idea to avoid a subscript out bounds
error for e.g. `#(a b c) fifth`.

#first however checks for an empty collection.

IHMO we can replace all occurrences of #checkedAt:
with #at:.

A quick recursive grep reveals that erudite uses #checkedAt:.
