Polyfills

[shaedrich]

Would it be a good idea to provide polyfills for engine versions without support for a specific function or tag?

To migrate this, we could use these overrides from watney by @ryanguill.

I think these could be added as examples

@pfreitag To easier distinguish polyfills from examples, "code sections" could be tagged. There are probably more types than just "example" or "polyfill":

• sample usage
• polyfill
• exceptions
• configuration
• etc.

That could also help with grouping, sorting and perhaps hiding "code sections"
