NAME

basis - use base with import call

VERSION

Version 0.05003

SYNOPSIS

Usage is similar to base or parent:

    package Baz;
    use basis qw/Foo bar/;

Or with arguments for import:

    package Foo;
    use basis Bary => [go => "away"];

DESCRIPTION

It uses Sub::Uplevel to do the construct

  BEGIN {
          use base qw/Foo bal/;
          Foo->import;
          bal->import('tor');
  };

transparently for the parent and child class.

If the classname is followed by a array reference, than the dereferenced array is used in the import call as argument.

Now it uses the import method from the class named in the global variable $basis::base. When not set from outside, this variable will be set during the first load of this module. It defaults to parent and as second alternative to base.

IMPORTANT NOTE

The call of Sub::Uplevel might come to late, so uplevel will not work as expected. If you use this module, the same rule as for Sub::Uplevel applies:

Use Sub::Uplevel as early as possible in your program.

Now this module croaks when Sub::Uplevel is not used earlier enough.
