NAME

SYNOPSIS

    use Silly::Die;
    EXPR or die trying;

DESCRIPTION

Instead of dying with a nasty punctuation variable ($!), you can now die with a simple, common English phrase: ``die trying''. What could be simpler?

Thus writing

    open FH, "foo" or die $!;

translates to

    open FH, "foo" or die trying;

Looks much better.

In addition, you can even customize the output of the trying function. When you load the module (with a use statement), pass in a subroutine reference. When you call trying, your sub reference will be invoked and passed the contents of $!. You can return anything you want, which will be then passed back to die. For example:

    use Silly::Die sub { qq(I died with: "@_") };
    open FILE, "foo" or die trying;

This prints out

    I died with: "No such file or directory" at ./test.pl line 9.

This is, of course, completely useless.
