Well, that isn't all there is to it.
Look, I'm not trying to convince you or Bob or Robert or anyone.
Seems much more like you folks are trying to tell me that I should be
positively ecstatic or something about the availability of this sort
of hack and that I should _happily_ use it in constrast to explicitly
forcing reference semantics.
It largely is a matter of _opinion_. Wrapping non structured
information _just to solve a mechanism problem_ in a structure is IMO
a misleading and inappropriate use of that sort of abstraction and the
supporting construct. It's a _hack_ as it has _nothing_ to do with
what you are trying to represent. Period. It is _equally_ a hack to
use explicit reference semantics. However, in the latter case, you
are at least using the construct for its _intended_ purpose. IMO,
that makes it less of a mess. Both are _messes_ as neither
communicates clearly what is really desired and both cause
"uglification" of the end result. However, IMO, the wrapping in a
structure approach is a greater mess due to its (IMO) inappropriate
and misleading nature.

No. Why should I?

Fine. Can you explain to me why I should believe _you_??? Because it
sure sounds like you think I _ought_ to.
