# The regression this is testing is that the first aelemfast, derived
# from a lexical array, is supposed to be a BASEOP "<0>", while the
# second, from a global, is an SVOP "<$>" or a PADOP "<#>" depending
# on threading. In buggy versions, both showed up as SVOPs/PADOPs. See
# B.xs:cc_opclass() for the relevant code.
