I can't say I have observed an _obsession_ with things like these.
Maybe it's just the fun or that it is so easy to Benchmark. :-)

That is certainly a stupid general rule because in some situations
this is exactly what you want: identifiers which do not need to be
created and which are not GC'ed.

As I said, I don't have made the same observation you apparently have
made.  I do not read most of the traffic here but if it really was
obsessive I think I would have noticed.  Strange how perceptions can
be so different.
