Question

I am trying to work through all the warnings in a Perl program, and having some trouble with this one.

Unquoted string "lib" may clash with future reserved word at /home/user/bin/ttt.v01.pl line 17.
    line 17: use lib ( "${HOME}/.lib" );
Unquoted string "sync" may clash with future reserved word at /home/user/bin/ttt.v01.pl line 23.
    line 23: our $SYNC_HOSTS = "${HOME}/.sync.hosts";
Unquoted string "config" may clash with future reserved word at /home/user/bin/ttt.v01.pl line 28.
    line 28: our $USAGE_TEXT = "[-hd] -a <config> -l <location>";

From perldiag:

Unquoted string "%s" may clash with future reserved word

(W reserved) You used a bareword that might someday be claimed as a reserved word. It’s best to put such a word in quotes, or capitalize it somehow, or insert an underbar into it. You might also declare it as a subroutine.

I have these all double quoted, and so I’m not sure what I’m missing.

Answer 1

Hmm, maybe you have an unmatched double quote before line 17, which cause the compiler to report wrong warnings?
