NAME
    Params::Smart - use both positional and named arguments in a subroutine

REQUIREMENTS
    The following non-core modules are required:

      Regexp::Common

INSTALLATION
    Installation can be done using the traditional Makefile.PL or the newer
    Build.PL methods.

    Using Makefile.PL:

      perl Makefile.PL
      make test
      make install

    (On Windows platforms you should use `nmake' instead.)

    Using Build.PL (if you have Module::Build installed):

      perl Build.PL
      perl Build test
      perl Build install

SYNOPSIS
      use Params::Smart 0.04;

      sub my_sub {
        %args = Params(qw( foo bar ?bo ?baz ))->args(@_);
        ...
      }

      my_sub( foo=> 1, bar=>2, bo=>3 );  # call with named arguments

      my_sub(1, 2, 3);                   # same, with positional args

DESCRIPTION
    This module provides "smart" parameter handling for subroutines without
    having to use a changed syntax or source filters. Features include:

    *   Mixed use of named and positional parameters.

    *   Type checking and coercion through callbacks.

    *   Dyanmic paramaters configured from callbacks.

    *   Memoization of Simple Paramater Templates.

  Compatability with Previous Versions

    Note that the formatting for simple parameter templaces has changed
    since version 0.03, and the complex paramater templates were not
    implemented until version 0.04, so it is best to specify a minimum
    version in use statements

      use Params::Smart 0.04;

    head1 REVISION HISTORY

    A brief list of changes since the previous release:

    0.06  Fri May  6 2005
            - corrected stupid glitch from Pod::Readme
    
    0.05  Fri May  6 2005
            - removed links to module manpages because the pod2text function
              stupidly changes L<Module> to "the Module manpage"
            - fixed bug that caused warnings in Regexp::Common
            - redid POD to use Pod::Readme
            - updated SEE ALSO section

    For a detailed history see the Changes file included in this
    distribution.

CAVEATS
    *This is an experimental module, and the interface may change.* More
    likely additional features will be added.

SEE ALSO
    This module is superficially similar in function to LMGetargs::Mixed>
    but does not require named parameters to have an initial dash ('-').

    Class::NamedParams provides a framework for implementing named
    parameters in classes.

    Sub::NamedParams will create a named-parameter wrapper around
    subroutines which use positional parameters.

    The syntax of the paramater templates is inspired by Perl6::Subs, though
    not necessarily compatible. (See also *Apocalypse 6* in Perl6::Bible).

    Sub::Usage inspired the error-messages returned by calls to arg().

    Params::Validate is useful for (additional) parameter validation beyond
    what this module is capable of.

    Class::ParmList provides a framework for paramater validation as well.
