The following regular expression gives a zero length match for the last match
in the string:

regex(r"\b([a-zA-Z_][a-zA-Z_0-9]*)\b(\s*\([^)]*\))?", "g");

Example:
auto r = regex(r"\b([a-zA-Z_][a-zA-Z_0-9]*)\b(\s*\([^)]*\))?", "g");
string text = replace("A ? B : C", r, "0");
writeln(text);

Expected output:
"0 ? 0 : 0"

Actual output:
"0 ? 0 : 0C"
