Nunjucks is rubbish

[michaeldfallen]

As a pattern library template language Nunjucks leaves a lot to be desired.

The key point of a pattern library is to include some sub-template that by default renders a component or element but allow for flexibility of overriding content, settings, behaviour.

Issues I've found with Nunjucks in this:

• macro syntax is very restrictive, only arguments passed in can be used in render
• calling a macro allows only one inner block of templating
• include syntax allows including a subtemplate but not overriding any blocks that template defines
• Jinjas with syntax is missing, meaning includes can't even get local scoped variables

Twigs embed syntax stuck for over a year now and would solve this if merged.

Suggest that we should fork nunjucks and merge the embed syntax, plus fix some other things like jinjas with syntax.

Did you do any of the above @michaeldfallen?
