how would you handle %EXPORT_TAGS and @EXPORT_OK?
Export-only-by-request (i.e. @EXPORT_OK) becomes the default.
The tag names become arguments to C<is export>:
sub foo is export(:BAR, :FOOLISH) {...} # Now in two named tagsets
Every exportable is automatically also in the :ALL tagset.
To export-by-default (i.e. the @EXPORT behaviour) you write:
sub foo is export(:DEFAULT) {...}
To export-in-all-cases (not currently possible) you write:
sub foo is export(:MANDATORY) {...}
See Perl6::Export for details and implementation (but bear in mind that those details are almost certain to change as a result of this very thread).
