A warning for subs that you declare but then don't use would be really annoying for those who are doing more advanced things behind-the-scenes. I might want to declare a subroutine name, but then define it at run-time.

In this case you declared two different subroutines names and only happened to use one. However, perl can't know that you are only going to use one until you are completely done with the program.

I don't run into this problem because I like parens that give perl a bit of extra help with the parsing (and keep maintenance programmers from getting too confused too). 

chk_timer( $_ ) for ...;
