Re^2: Constants and Subclasses...

Does require call the import()? In any case, I was about to answer the Exporter, but I think to make that less sucky you'd want to use EXPORT_OK and/or EXPORT_TAGS instead. So the child class could use them explicitly if it wanted to. That's probably pretty obvious I guess.

But, I always use base qw(Exporter) to get the exporting to actually happen. I've never tried it with require. Does the require work? [update: thanks ferreira]

No, `require` does not call `import()`. And you reminded me I wanted to include Exporter in the `@ISA` array so that the parent class inherited the `import()` method from Exporter (which is why this module came into the answer). This is almost equivalent to `use base qw(Exporter)` (but not identical). See the docs of base. Also, if the symbols were added to `@EXPORT_OK`, they should be explicitly mentioned as arguments of `import`. To keep the answer in line with the question, using `@EXPORT` is the easiest thing to do.	[reply]
