people who still use "".format() instead of fstrings in python 3 are perverts who will not see the kingdom of heaven

we just use formatted sql files, but you could probably do the same w/fstrings. e.g.
template.sql
SELECT *
FROM schema.table
WHERE {filter_expression}
script.py
(
open('template.sql')
.read()
.format(
filter_expression='value = 1'
)
)
template.sql
SELECT *
FROM schema.table
WHERE {filter_expression}
script.py
(
open('template.sql')
.read()
.format(
filter_expression='value = 1'
)
)

C++ is a lot nicer with variable interpolating fstrings and the ability to concisely test cross products of flow control.

Yeah, that's what I've been using, it's just a lot less flexible than fstrings.

It's performance-driven. FNames are auto-hashed and meant to be used for lookups. FTexts are localizable and optimized for presentation retrieval. FStrings are general purpose for convenient buffer lifetimes/manipulation.

I’m in no way a coder but when I came across fstrings I felt an aesthetic objection. It seems such a language hack (though useful it seems)

100% agree R needs native fstrings. I don’t use {glue} (for various reasons) and work quite a bit in JS these days, and really miss that feature in R.

Python fstrings are apparently interpreted and executed in-situ and render as strings, meaning string ops and methods can be performed on them.

Modern debugging tools are amazing
I still have no idea why this sort isn't working
It SHOULD be. It looks fine! The execution goes past "Combat.Attacks" and hits the Closers vs Grounds vs Airs bit each time and continues.
But every time I run this, the resultant TMap order is randomly thrashed?

{
// (why yes, we ARE in-place converting these FGameplayTags to FNames and then FStrings like a billion times!)
FString AStr = A.ToString();
FString BStr = B.ToString();
for (int index = 0; index < AStr.Len(); index++)
{
if (index >= BStr.Len()) { return true; }
// This is broken out because the logic is so dense, I found 3 separate bugs in here initially, so it can have some debugging space, as a treat
char AChar = tolower(AStr.GetCharArray()[index]);
char BChar = tolower(BStr.GetCharArray()[index]);
