Re: Strict error on var when using Mail::SendMail

It's not actually an error, and it's not strict that's complaining. It is in fact a warning, and diagnostics warns you.

I don't think the diagnostics pragma allows you to selectively disable its messages, like you can with e.g. no warnings 'once', but you can turn all diagnostics off and on:

use diagnostics;

disable diagnostics;
do_naughty_stuff();

enable diagnostics;
do_nice_things();

For more details, see the manuals for diagnostics and warnings.

That doesn't work for two reasons. `disable diagnostics;` only affects run-time warnings. "used only once" is a compile-time warning. `disable diagnostics;` doesn't disable the warning, just the diagnostic. So while `disable diagnostics;` would remove the diagnostic message, the basic warning message would still be displayed. The solution is to eliminate the warning (using `no warnings 'once';` for example), since there's no diagnostic message if there's no warning.	[reply] [d/l] [select]
