:thought_balloon: Would you like to apply a source code transformation result which can be generated also by a command like the following? (:point_right: Update candidates in 12 lines)
[Markus_Elfring@fedora lokal]$ perl -p -i.orig -0777 -e 's/^(?<indentation>\s+)(?<target>\S+)\s*=\s*\k<target>\s*(?<operator>[+\-%&|^@]|\*\*?|\/\/?|<<|>>)/$+{indentation}$+{target} $+{operator}=/gm' $(find ~/Projekte/SLY/lokal -name '*.py')
Does this make any different at all in SLY performance?
I guess that a corresponding run time difference would be measurable. Can you find further software fine-tuning desirable then? :thinking:
Why do these changes matter?
:thought_balloon: I suggest to reconsider your development concerns also according to information from the Python enhancement proposal 577 (from 2018-05-14).
Why does this matter?
Can you accept the explanation from the Python documentation (which you probably know already)?
“…
In the augmented version, x
is only evaluated once. Also, when possible, the actual operation is performed in-place, meaning that rather than creating a new object and assigning that to the target, the old object is modified instead.
…”
:thought_balloon: Do you accordingly expect positive effects for the software run time characteristics?
@jpsnyder : :thought_balloon: Would you confirm that a synthetic version of the human mind can produce suggestions that are valid in the context of software development?
:eyes: Some source code analysis tools can help to find opportunities for improving software components. :thought_balloon: I propose to increase the usage of augmented assignment statements accordingly.
Would you like to integrate anything from a transformation result which can be generated by a command like the following? (:point_right: Please check also for questionable change suggestions because of an evolving search pattern.)
