One other reason I sometimes temporarily turn on `diagnostics` is to find out what keyword to use when I want to selectively turn off a particular group of warnings. For example, in this case yo see that the body of the diagnostic message begins with `(D deprecated)`. If for some reason I wanted to turn off such warnings in a suitably narrowed scope, I would do this: `use strict; use warnings; # ... { no warnings 'deprecated'; %hash->{ silly } = 'foo'; }` [download] Granted, I can't think of any good reason for turning off this particular warning (except perhaps globally on a large body of legacy code), but there are more realistic examples. E.g.: `use strict; use warnings; require Exporter; { no warnings 'once'; import = \&Exporter::import; }` [download] The `no warnings` above silences a warning of the form `Name "main::import" used only once: possible typo...` [download] Yes, one could silence this* warning like this instead: `import = import = \&Exporter::import;` [download] ...but I digress. the lowliest monk	[reply] [d/l] [select]

If you're ever unsure as to what a warning means, you can ... `use diagnostics;` [download] which would print the exact text as posted in the the first reply.	[reply] [d/l]
