Perhaps to someone as clever and knowledgeable as yourself. But to most
people, writing:
classify $var => 'ClassName';
is considerably less complex than writing a nontrivial package and tie()ing
a scalar to it.

It didn't support those things as it was written but, yes, of course it
*could* support them with extra coding...at the expense of making the
STORE even more complex.

Of course. My point was that the complexity of the tie() mechanism (and yes,
for many folks back in the Real World, tie() is firmly in the Too Hard basket)
makes people not want to learn it. Hence they are unable to whip up a custom
TIESCALAR/FETCH/STORE suite when they need it.

But within its (humble) domain my package is so much easier to learn and
to use than tie(). For many people *that* is a killer argument.

PS: I'm not sure why we're even debating this. I'm not putting this
forward as a replacement for tie(), I'm not claiming this is the
Only Way To Do It, I'm not even suggesting the module go into the
core. I'm just reporting back to P5P on (what I believe to be) a
useful module that was the outcome of a thread that went offline.
It saddens me that everything on P5P has to be so adversarial, and
shames me that I could so easily be caught up in the disputation.
Unlike the departures of Chip and Graham and Jarrko, mine would be
no loss to this list, but (for my own sake) maybe I need a break
from P5P too...
