NAME
    warnings::method - Produces warnings if methods are called as functions

VERSION
    This document describes method version 0.02

SYNOPSIS
        use warnings::method; # or use warnings::method 'FATAL';

        package Foo;
        sub bar :method{
            # ...
        }

        Foo::bar(); # WARN: 'Method Foo::bar() called as a function'
        Foo->bar(); # OK

DESCRIPTION
    This pragmatic module produces warnings if methods are called as
    functions. Here, *methods* are subroutines declared with the :method
    attribute.

    This module scans compiled opcode tree, checks subroutine calls and
    warns when dangerous function calls are detected. All the processes
    finish in compile time, so this module has no effect on run-time
    performance.

INTERFACE
  "use/no warnings::method;"
    Enable/Disable the "method" warnings. These are equivalent to "use/no
    warnings 'method'" if "warnings::method" is already loaded.

DEPENDENCIES
    Perl 5.8.1 or later, and a C compiler.

BUGS AND LIMITATIONS
    No bugs have been reported.

    Please report any bugs or feature requests to
    "bug-warnings-method@rt.cpan.org/", or through the web interface at
    <http://rt.cpan.org/>.

    functions.

    as a function

    function
