# Consider two kinds of magic :
# A : PERL_MAGIC_uvar, with get (but no set) magic
# B : PERL_MAGIC_ext, with a zero vtbl
# If those magic are attached on a sv in such a way that the MAGIC chain
# looks like sv -> B -> A -> NULL (i.e. we first apply A and then B), then
# mg_magical won't turn SvRMAGICAL on. However, if the chain is in the
# opposite order (sv -> A -> B -> NULL), SvRMAGICAL used to be turned on.
