Test2::Event::TAP::Version - Event for TAP version. Both functions require and use call the eval function to process the code. The Perl interpreter has a list of directories in which it searches for modules (global array @INC). Both use the list of search paths in @INC to find the module. Package declarations apply package scope till the next package declaration or the end of the block in which the declaration is made. Namespaces prevent variable name collisions between packages, Packages enable the construction of modules which, when used, won't clobbber variables and functions outside of the modules's own namespace, package statement switches the current naming context to a specified namespace (symbol table).
