I get the same output with or without "g" flag at line 6:

So I don't understand when I have to use "g" flag.
My bet is that Regex results in D are lazy so "g" doesn't make
sense in this context however I'm able to see an effect with
"match":
match("12000 + 42100 = 54100", regex(r"(?<=\d)(?=(\d\d\d)+\b)",
"")).writeln;
match("12000 + 42100 = 54100", regex(r"(?<=\d)(?=(\d\d\d)+\b)",
"g")).writeln;
matchFirst would be like without "g"
matchAll would be like with "g"
I should have read the doc more thoroughly:
https://dlang.org/phobos/std_regex.html#match
Delegating the kind of operation to "g" flag is soon to be
phased out along with the ability to choose the exact matching
scheme.
So case closed for me
