Description

Perl by default just ignores cycles in require statements - if Foo.pm does use Bar and Bar.pm does use Foo, doing use Foo elsewhere will start loading Foo.pm, then hit the use statement, start loading Bar.pm, hit the use statement, notice that Foo.pm has already started loading and ignore it, and continue loading Bar.pm. But Foo.pm hasn't finished loading yet, so if Bar.pm uses anything from Foo.pm (which it likely does, if it's loading it), those won't be accessible while the body of Bar.pm is being executed. This can lead to some very confusing errors, especially if introspection is happening at load time (make_immutable in Moose classes, for example). This module generates a warning whenever a module is skipped due to being loaded, if that module has not finished executing.

This module works as a pragma, and typically pragmas have lexical scope. Lexical scope doesn't make a whole lot of sense for this case though, because the effect it's tracking isn't lexical (what does it mean to disable the pragma inside of a cycle vs. outside of a cycle? does disabling it within a cycle cause it to always be disabled for that cycle, or only if it's disabled at the point where the warning would otherwise be generated? etc.), but dynamic scope (the scope that, for instance, local uses) does, and that's how this module works. Saying no circular::require enables the module for the current dynamic scope, and use circular::require disables it for the current dynamic scope. Hopefully, this will just do what you mean.
