In the past, I think the analysis was always "no". It adds
an opcode, so increases the size of the switch, causing
more pressure on the cache, with an overall questionable
effect.

As for measuring the effect of the change: how often
does that pattern occur in the standard library?
(compared to what total number of LOAD_ATTR)

Regards,
Martin
