Re^2: PERL modules named differently than the package won't export

Oh, yeah one more thing.

Most functions are not exported; they have to be explicitly referenced (to avoid too much namespace pollution). But there are two or three that are used so often it just makes more clutter to require explicit reference.

I see. I guess that makes (some) sense. How about this approach, then: As Eliya mentioned, `use Utils1;` is equivalent to `BEGIN { require Utils1; Utils1->import; }` [download] You should, therefore, be able to make the import from the Utils package transparent by editing Utils1.pm to do something along the lines of `package Utils1; sub import { Utils->export_to_level(1, @_); } package Utils; ...` [download] This will (assuming I remembered the incantation correctly) make `Utils1->import` equivalent to `Utils->import`. Although, really, the better approach would likely be to put the two versions of `Utils.pm` into different library directories (e.g., `/usr/local/devel/Utils.pm` and `/usr/local/stable/Utils.pm`), then manipulating `@INC` (by setting `PERL5LIB` in the shell or with `use lib` in the code) so that each program will load the appropriate version.

Utils1->import

Utils->import
