I wasn't aware that qr// returned a blessed reference, rather than just a
reference. It's not obvious from any of the documentation that I've read
(Scalar::Utils, perlop, and perlfunc, among others) that the difference is
between the underlying structure and the pseudo-class (perldoc doesn't seem
to know about the Regexp package/class).
Please update the documentation to note the single, unexpected difference
from ref:
Note: reftype(qr/abc/) differs from the ref(qr/abc/). The former returns
the name of the underlying structure, in all capitals: "REGEXP"; while the
latter returns the name of the pseudo-class in mixed case: "Regexp".
