Nested Blocks and locals in includes

Hi,

two more questions:

Is it possible to put a block inside a block?

I tried something like this and it doesn't work:

block(name='content')
  h1 Hello world!
  block(name='subcontent1')
  h1 Hello Olli!
  block(name='subcontent2')

Is it possible to include something depending on a variable.

I tried something like this and it doesn't work:
```
include(src='includes/lectures/{{ name }}.sgr')
```

The background is the following:

I would like to generate my site https://ob.cs.hm.edu/ using spike.
Code can be found at https://github.com/obcode/ob.cs.hm.edu/tree/spike.
Some pages under /lecture have the same structure, but different content. I would like to use one
layout and "inject" the content. I can do it via locals, but some parts are larger than just one value.
