in reply to How to read a file and add value for same key

Just for the fun of it:

$_=<>; 1 while (s/(\w)\s(\d+)(.*)(\s\1\s)(\d+)/$1." ".($2+$5).$3/e); print

Example call:

$ cat test a 1 b 3 c 5 a 2 $ ./samekey test a 3 b 3 c 5 $ cat anothertest a 1 b 3 c 5 a 2 a 3 b 3 c 5 $ ./samekey anothertest a 6 b 6 c 10

[choroba]: Email::Address DoS
[Corion]: (that module has been deprecated by its author already, so that's fair. Although I wonder why the backtracking can't be fixed to handle the formfeeds gracefully)
[choroba]: not enough tuits?
[Corion]: choroba: Yeah, maybe. I'm also unaware of who uses Email:: modules, but that's more my limited horizon of things ;)
[Corion]: Ah - there even is the replacement of Email::Address::XS , by the bug reporter, which hopefully fixes this bug already ;)
