[cmrschwarz]

Fixes a simple bug in path lookup.

Testcase

(input: {"foo": [42], "bar": [1,2,3]})

let input = r#"
{{#each bar as |x|}}
{{#each ../foo as |y|}}
{{../../foo.0}}: {{../x}}
{{/each}}
{{/each}}
"#;

Output Before

42: 
42: 
42: 

Output After

42: 1
42: 2
42: 3

LGTM. Thank you!

I'm curious that did you find this in your scenario or using some test suites?

LGTM. Thank you!

I'm working on a real usecase were I'm creating an interactive debug log/display for a rather complex data processing tool.
All the fixes that I'm PR'ing are just stuff that I run across while developing that tool.
I would like to avoid maintaining a fork of this project, so this is just open source working as intended 😆.
That process is nearing it's completion now, but I still have a few things on my personal branch. I hope to manage to PR these over the week / weekend. Maybe I can find a good solution for the if indentation thing (#650) too, have you looked at that a bit?

Thank you! I haven't got enough time to look into the if indent fix. Any issue with indent requires me to switch my context and deep dive into it :)

I will take a look in this weekend.
