These are coming in fine because they are not handled by Mailman's filtering rules. And the reason for the holds is they are being flagged for " Message has implicit destination". On Fri, Mar 13, 2020 at 8:06 AM Marco Sulla < python-ideas@marco.sulla.e4ward.com> wrote:

Well, probably it depends by two possible errors:

1. sometimes I send directly to python-ideas@python.org. This way my real address is used, and the system does not recognize it. I saved the "correct" address to my contact list, so now it's more simple to not do this mistake

2. I noticed that I can't put the address of the list in the CC field. Probably this is a problem of e4ward. Now I put it every time in the To: field

PS: this message, for example, has some problems? I put the "correct" list address in the To field. PPS: maybe it's more simple to create a marco_sulla_python@gmail.com address....

Hi Marco,

all I can do is tell you what I’m seeing. Some of your posts go through

fine, and others haven’t.

...

I’ll approve your posts when I have time (almost always within 24 hrs),

but some might be delayed.

Hello. I'm simply using e4ward, a disposable email address service, to avoid spam. I always used e4ward in past, with every mailing list, and also with Python mailing lists. Furthermore I'm using e4ward also with Python List mailing list in the current time, and I have no problem.

Well, so all this discussion is only for freeing _one_ memory

Seriously... as the other users already said, if someone really need it, he can use normal loops instead of comprehensions and split complex expression so temporary objects are immediately free. Furthermore, 2x speedup observations are done by benchmarks. In the real world, how can you be sure that L2 cache is not already filled up? :-)
