in thread index regex

If 5.10+ is available, use of the  //p regex modifier allows  ${^MATCH} (and friends) to be used eliminating the need for an explicit capture and perhaps slightly speeding the matching:

>perl -wMstrict -lE "my $line = q{as specified, line has: no digits (0-9); letters!}; ;; say qq{'${^MATCH}' found at $-[0]} while $line =~ m{ [ (),.;:?!-] }xmsgp; " ' ' found at 2 ',' found at 12 ' ' found at 13 ' ' found at 18 ':' found at 22 ' ' found at 23 ' ' found at 26 ' ' found at 33 '(' found at 34 '-' found at 36 ')' found at 38 ';' found at 39 ' ' found at 40 '!' found at 48
