Re^3: Library file or module for sharing code? (import)

The only important part that was missing was

@ISA= qw(Exporter);
[download]

But a better approach would be either:

*import= \&Exporter::import;
[download]

or, if you know you'll have a new enough version of Perl

use Exporter qw(import);
[download]

Because using inheritance to get a single method is a bad idea; it brings along too much unhelpful baggage.

Thanks tye, went with: `import= \&Exporter::import;` [download] which worked fine (though I have no idea what is going on there--nothing in the docs I could find :) —Brad "The important work of moving the world forward does not wait to be done by perfect men."* George Eliot	[reply] [d/l]

It just imports the `import()` sub "by hand" from Exporter.pm. `use Common qw(Foo);` becomes `BEGIN { require "Common.pm"; Common->import("Foo") }` and `Common->import(...)` can find the `import()` by inheritance (`@ISA`) or because Common::import itself has been defined. "Importing" just makes Common::import() another name for Exporter::import(). - tye	[reply] [d/l]
