nested loops

[Krastanov]

I have a Jekyll website that heavily uses nested loops over complicated page variables as a way to generate a page. I was surprised to see that does not work in Franklin. What is the idiomatic way to do the following (pseudocode):

# file utils.jl

myvariable_d = [Dict("a"=>[1,2]),Dict("a"=>[3,4])]
myvariable_v = [[1,2],[3,4]]

# file homepage.md

{{for group in myvariable_d}}
{{for i in group["a"]}}
## {{fill i}}
{{end}}
{{end}}

{{for group in myvariable_v}}
{{for i in group}}
## {{fill i}}
{{end}}
{{end}}

As soon as you have complexity like this you should move the logic to a hfun and just write Julia code for it (or if you want to keep things in the same page and not move it to utils.jl, use a hidden executed code block; or lastly you can create an unnested iterator at the definition level)

The next version will allow for a bit more flexibility in these things but the purpose is just to be more consistent, not to allow gradually more complex logic in a kind of specialised DSL like in Hugo.

Thanks! Closing the issue, but feel free to move it to discussion or QnA if appropriate.
