NAME
    `Struct::Dumb' - make simple lightweight record-like structures

SYNOPSIS
     use Struct::Dumb;
 
     struct Point => [qw( x y )];

     my $point = Point(10, 20);

     printf "Point is at (%d, %d)\n", $point->x, $point->y;

     $point->y = 30;
     printf "Point is now at (%d, %d)\n", $point->x, $point->y;

DESCRIPTION
    `Struct::Dumb' creates record-like structure types, similar to the
    `struct' keyword in C, C++ or C#, or `Record' in Pascal. An invocation
    of this module will create a construction function which returns new
    object references with the given field values. These references all
    respond to lvalue methods that access or modify the values stored.

    It's specifically and intentionally not meant to be an object class. You
    cannot subclass it. You cannot provide additional methods. You cannot
    apply roles or mixins or metaclasses or traits or antlers or whatever
    else is in fashion this week.

    On the other hand, it is tiny, creates cheap lightweight array-backed
    structures, uses nothing outside of core. It's intended simply to be a
    slightly nicer way to store data structures, where otherwise you might
    be tempted to abuse a hash, complete with the risk of typoing key names.
    The constructor will `croak' if passed the wrong number of arguments, as
    will attempts to refer to fields that don't exist.

     $ perl -E 'use Struct::Dumb; struct Point => [qw( x y )]; Point(30)'
     usage: main::Point($x, $y) at -e line 1

     $ perl -E 'use Struct::Dumb; struct Point => [qw( x y )]; Point(10,20)->z'
     main::Point does not have a 'z' field at -e line 1

FUNCTIONS
  struct $name => [ @fieldnames ]
    Creates a new structure type. This exports a new function of the type's
    name into the caller's namespace. Invoking this function returns a new
    instance of a type that implements those field names, as accessors and
    mutators for the fields.

  readonly_struct $name => [ @fieldnames ]
    Similar to `struct', but instances of this type are immutable once
    constructed. The field accessor methods will not be marked with the
    `:lvalue' attribute.
