I get the same output with or without "g" flag at line 6: https://run.dlang.io/is/9n7iz6 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"
