Consider laxy

[jamestalmage]

While not my intention when initially creating laxy, it ended up being a drop in replacement for this module.

It has a few key advantages:

• It's a more generalized Proxy generator. Allowing for any generator function (not just require), and allows passing any number of arguments.

• It implements much more of the Proxy API. Allowing things like Object.keys, Object.getPrototypeOf, setting values, and reflecting on property descriptors of the underlying object, etc.

• laxy(require)('modulePath') will work exactly as this module does, so the API is a drop in replacement.

• Proxy can be made to respond correctly to typeof (import-lazy will always report 'function' regardless of the proxied object).

• Support for revocable proxies.

• It has a fun name.

Obviously not all of those are applicable to the goal of lazy importing, but there are a few items worth porting here at a minimum.
