Version
    This documents version v0.3.$Rev: 6 $ of Unexpected

Description
    An exception class that supports error messages with placeholders, a
    "throw" in Unexpected::TraitFor::Throwing method with automatic re-throw
    upon detection of self, conditional throw if an exception was caught and
    a simplified stacktrace

Configuration and Environment
    Applies exception roles to the exception base class Unexpected. See
    "Dependencies" for the list of roles that are applied

    Error objects are overloaded to stringify to the full error message plus
    a leader if the optional "ErrorLeader" role has been applied

    Defines these attributes;

    "class"
       Defaults to "__PACKAGE__". Can be used to differentiate different
       classes of error

Subroutines/Methods
  BUILDARGS
    Placeholder to shut Pod::Coverage up

  BUILD
    Does nothing placeholder that allows the applied roles to modify it

  is_one_of_us
       $bool = $class->is_one_of_us( $string_or_exception_object_ref );

    Class method which detects instances of this exception class
