Re: using $! for die()ing with Package function

[JupiterHost.Net]

I think as long as a failed open() or mkdir() (IE a system function that
does $! sets it already) then that is all I need for this project:

sub baz {
   mkdir '/dir/I/cant/make' or return;
}

will do what i need:

baz or die $!;

Actually mkdir returns true or false -

sub baz{return mkdir '/dir/I/cant/make';}

would do the same without any evaluation.

good point!

$ cat baz.pl
#!/usr/bin/perl
use strict;
use warnings;

baz() or die $!;

sub baz {
  mkdir 'faz/shaz/waz/daz';
}
$ perl baz.pl
No such file or directory at baz.pl line 5.
$

Although I'd need to 'or return' if it wasn't last thing in the block

$ cat baz.pl
#!/usr/bin/perl
use strict;
use warnings;

baz() or die $!;

sub baz {
  mkdir 'faz/shaz/waz/daz';
  return 1;
}
$ perl baz.pl
$

$ cat baz.pl
#!/usr/bin/perl
use strict;
use warnings;

baz() or die $!;

sub baz {
  mkdir 'faz/shaz/waz/daz' or return;
  return 1;
}
$ perl baz.pl
No such file or directory at baz.pl line 5.
$

Thanks!
