Re^2: Making it clearer to say that a sub is defined within current package

It's definitely possible to tell in which package a sub was declared.

I saw it in the book perlhacks and IIRC it's available in B

The problem I see is that My:: is global, you would need the hint hash to restrict it's effect only to the file importing My.

Well that's an issue if you want to set My::Dumper = Data::Dumper::Dumper once and for all. But if the only function defined in my is My::AUTOLOAD, and it always checks the calling package you should be fine wouldn't you? (At execution time at least, you'd lose compilation time errors with My::function() instead of function())	[reply]

In a clean design you don't want My:: to have effect outside the scope using it. Also probably a lowercase name my:: for pragma would be more appropriate to avoid a clash with cpan modules.

Checking caller and dying when the function does not exist in the caller package wouldn't be much different than dying when calling an undefined function with the package prefix. The main problem is that calling local functions as my::something() makes strict's job harder.	[reply]
