Should the 'Possible unintended interpolaton' item in perl56delta.pod also be included in perldiag.pod for use with diagnostics pragma? Noticed it in both 5.6.1 and 5.7.2@11683. Simple case, where diagnostic message does not print: $ perl -Mdiagnostics -e 'print "ksm@dca.net\n"' Possible unintended interpolation of @dca in string at -e line 1. Name "main::dca" used only once: possible typo at -e line 1 (#1) (W once) Typographical errors often show up as unique variable names. If you had a good reason for having a unique name, then just mention it again somehow to suppress the message. The our declaration is provided for this purpose. ksm.net -Ken
