I like to get clever with snippets, and it would be great to be able to create dynamic snippets for different circumstances by being able to nest one snippet within the creation script of another. That way I can parse individual functionality in different snippets, but build them together to create more complex dynamic snippets without having to maintain the same basic code in multiple individual scripts.

I could see this working simply like:

snippet1:
DoThing;

snippet2:
$snippet1$
DoMoreThing;
