Re: Caching a default instance to avoid initializing it every time (with Moo)

This is a Singleton pattern, and that is how you should implement it. For instance, let there be a sub instance which either returns a cached copy or creates a new instance and caches it. Don't try to do this in a constructor or a wrapper around it – you will confuse other people, at best. Give them what they are conditioned to expect to see. You also need to be very sure that you are storing the cached instance in a persistent global variable as you think you are.

Give them what they are conditioned to expect to see. Throwing a colander of ~~words~~ spaghetti at the wall and managing to have a piece stick is perhaps a valid approach to problem solving but so is doing blockchain in pencil and paper. You also need to be very sure that you are storing the cached instance in a persistent global variable as you think you are. Where is your example code to test this stern advice? If it was worth saying, it's worth showing. It is insulting that, again, there were three working, technical answers presented before your reply and you still felt the need to chime in, adding nothing. Then again, maybe you can't read the code in the three examples so you might not have realized the question was trebly answered already.	[reply]
