Re^2: Accessing a module's method without causing circular dependency

Oh, so I guess I misunderstood how the use statement itself works. I have to read the manual for it again. So does that mean when you say "use <some module>", if it is already loaded, Perl does not load it again? If that is the case then I guess I don't have to worry here. Thanks.

Correct. The module is neither compiled nor executed a second time, although it's `import` method is called every time `use` is used (unless prevented using `()` or `qw()`). `use`: "The `require` makes sure the module is loaded into memory if it hasn't been yet."	[reply] [d/l] [select]
