My style highly depends on the intended users, and how often it will be used. If it's a program I distribute, or write for someone else to use, I use something like: 
    open my $fh => $file or die "Failed to open file '$file': $!\n";

[download]
If it's code I just write for myself, I use something like: 
    open my $fh => $file or die "open: $!\n";

[download]
or 
    open my $fh => $file or die "open '$file': $!\n";

[download]
depending on how many files the program opens.

If it's a 'write-today-discard-tomorrow' program, I use: 

    open my $fh => $file or die "$!\n";

[download]
or even 
    open my $fh => $file or die;

[download]
I use the latter style when writing on the command line too.

Note that (except in the last case) I include a trailing newline. Most of the time, I couldn't care less on which line of the program an error occurs, especially not when it's about opening files.

I've been writing some C lately, and I've started appreciating perror. Perhaps I should write a little module give similar functionality.
