only

If you're looking for a Perl module that allows you to load a specific version of a module only if it satisfies a given condition, then 'only' is what you need. With 'only', you can specify a single version, which will load only the module matching that version. Alternatively, if you want to specify multiple versions, 'only' will load any of those versions.

'Only' supports a variety of different conditions, which you can use to refine the module loading process. For example, you can tell 'only' to only use a module if its version is between 0.30 and 0.50, but not 0.36, or if the version is greater than or equal to 0.55.

'Only' also provides functionality for installing a particular version of a module, even if multiple versions of the same module are installed. With 'only', you can easily install and use many different versions of the same module by following a few simple steps.

To use 'only' as part of your code, you can use the SYNOPSIS section provided in the documentation. This section provides examples of how to use 'only' and what kind of arguments and options you can pass to it. For example, you can use 'only' with specific modules and version conditions or use it globally to set options.

If you prefer to use 'only' in an object-oriented way, you can do that too! The module provides an object-oriented interface that allows you to specify the module and its version condition, add and remove conditions, and install an alternate version of a module easily.

Overall, 'only' is a powerful and easy-to-use module that can help you manage your Perl modules and keep them under control. Whether you're developing a new project or trying to maintain an old one, 'only' is the perfect tool for the job.
