Wise ones: I tie a hash to an existing file with:
tie (%hash, DB_File', "myfile") or die "Can't open $filename: $!\n";
I'd now like to delete the entry (and key!) whose key is, say,
"foo". I read in What's the difference between "delete" and "undef" with hashes? about delete and undef, but it says that
tied databases may not do delete and undef as normal hashes do.
Any suggestions?
