man I wish someone had taught me composite pattern earlier.

What do you find it useful for?

@AmyShackles being able to build nested trees without much complexity. I once had to build tree that had to grow on both Main and Cross axis and it was a recursion hell.

@useVim 0.0 I am intrigued.

Lots of implementation of an interface, all wrapped in a single 'composite' which also implements the same interface.

Everything I know about design patterns is just scraped together 3rd hand on the job... the above might be vaguely right tho...
