Description of the "And" Experimental feature for RSpec/Given (was "Also")
# Experimental And Clauses
#
# I've been thinking about tests where there are multiple Thens
# in a single context. All the Givens and before blocks are run
# for each Then. Since Then's are idempotent, that seems to be a waste.
#
# Maybe we can introduce And clauses. They are like Then clauses, but
# they reuse the Givens of an existing Then clause. This could make a
# difference in spec that have expensive setups.
