Implement exporter tags support

[johndaviddunlap]

This would be a very nice feature to have. In our application, we have a Util module which contains a lot of helper functions which we import into all of our other modules. For example,

In Util module

use vars qw(@EXPORT_OK);
use Exporter qw(import);
@EXPORT_OK = qw(
    is_uuid
    assert_uuid
    assert_numeric
);

In some other module

use Lariat::V4::Util qw(
    is_uuid
    assert_uuid
    assert_numeric
);

Currently, what we see in the IDE is as follows:

This is not about tags and this should work already. @EXPORT and @EXPORT_OK already supported. This issue is about @EXPORT_TAGS

[johndaviddunlap]

My apologies, I followed the link on #1560. I must have misunderstood the issue.

ping?.. This and the support for indirect reference, e.g.

my @arr = qw/sub1 sub2/; @EXPORTER = @arr;

are dearly missed for me.

Maybe when the variable, or a sub is explicitly imported, such as

use Module qw($VAR);

and later

print $VAR, "\n";

it can pick the resolution from the usage statement.

[hurricup]

It does, if plugin understands, how export been done. See Carp for example. If some tricky export been used, it requires additional efforts from my side to make it work

[morehockeystats]

Did you have a chance to work on this one?

It should be nice to resolve the "Unable to find sub definition" when importing a tag.
