how NOT to import exported subs/variables from a module?

jfroebe has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

Is there a way to either override or ignore the export of variables/subroutines from a module? I ask because sometimes I run into modules either in CPAN or some homebrew monstrosity where the namespaces collide.

thanks

From the docs... `perldoc -f use ... If you do not want to call the package's "import" method (for instance, to stop your namespace from being altered), explicitly supply the empty list: use Module ();` [download] This should do it. Sandy	[reply] [d/l]

The next two lines of that documentation are: `That is exactly equivalent to BEGIN { require Module }` [download] So unless you need the compile time action from `BEGIN`, plain `require` works also. It's only one extra character over `use` with an empty list and I find it stands out better visually as being a module load without import side-effects. -xdg Code written by xdg and posted on PerlMonks is public domain.

It's only one extra character over use with an empty list and I find it stands out better visually as being a module load without import side-effects. That's interesting. I would far prefer `use Module ()` since it explicitly says to me "I am deliberately not importing anything' where `require Module` might be saying any of: I don't want to run at compile time I don't want to run import() yet I don't want to run import() at all (for whatever reason) I don't want to run import() because I don't want to add any subs/variables to my namespace	[reply] [d/l] [select]
