 };

 my $data = { 
     'foo' => 'bar',
     'fibble' => [qw/wibble bibble/],
 };
 try{
     Exception::Simple->throw( 
         'error' => 'oh noes!',

 try{
     Exception::Simple->throwc( "Some::Fake::Exception::Class", 'oh noes!' );

     warn $_; #"oh noes!"
     warn ref( $_ ); #"Some::Fake::Exception::Class"
     warn $_->error; #"oh noes!"

     'fibble' => [qw/wibble bibble/],

 try{
     Exception::Simple->throwc( 
         'Some::Fake::Exception::Class',
         'error' => 'oh noes!',
         'data' => $data,
     );

DESCRIPTION

pretty simple exception class. auto creates argument accessors. simple, lightweight and extensible are this modules goals.

METHODS

throw

with just one argument $@->error is set Exception::Simple->throw( 'error message' ); # $@ stringifies to $@->error

or set multiple arguments (creates accessors) Exception::Simple->throw( error => 'error message', data => 'cutom atrribute', ); # warn $@->data or something

throwc

Same as throw, except the first argument is a classname which will become the classname of the exception object.

Useful for throwing specific execptions without having to create lots of packages.

try{
    Exception::Simple->throwc( "Some::Fake::Exception::Class", 'oh noes!' );
} catch {
    warn ref( $_ ); #Some::Fake::Exception::Class
};

WARNING: using throwc with a real classname is unsupported i.e. throwc( "Data::Dumper", "derp" ) #you just made god kill a kitten

rethrow

say you catch an error, but then you want to uncatch it

use Try::Tiny;

try{
    Exception:Simple->throw( 'foobar' );
} catch {
    if ( $_ eq 'foobar' ){
    #not our error, rethrow
        $_->rethrow; 
    }
};

error

accessor for error, if its been set
