> I appreciate the PR with change of documentation, but I still see it as an
inconsistency that
{{ var.json.somekey.somecontent } works
and
{{ var.json.get('somekey.somecontent', false)
Doesn’t.
In this cases `var.json` is references to object (dictionary) and other part
it is the way how you could access `__getitem__` in [Jinja
Variable](https://jinja.palletsprojects.com/en/3.1.x/templates/#variables).
Some native Jinja templates sample
```python
import jinja2
environment = jinja2.Environment()
var = {"a": {"b": {"c": 1 }}}
template = environment.from_string("Sample a.b.c = {{ awesome_var.a.b.c }}")
print(template.render(awesome_var=var))
# Sample a.b.c = 1
template = environment.from_string("Sample ['a']['b']['c'] = {{
awesome_var['a']['b']['c'] }}")
print(template.render(awesome_var=var))
# Sample ['a']['b']['c'] = 1
template = environment.from_string("Sample mixin = {{
awesome_var.get('a')['b'].c }}")
print(template.render(awesome_var=var))
# Sample mixin = 1
template = environment.from_string("Sample by key = {{
awesome_var.get('a.b.c', 'Foo') }}")
print(template.render(awesome_var=var))
# Sample mixin = Foo
template = environment.from_string("Sample by pseudo json-path = {{
awesome_var.get('a.b.c') }}")
print(template.render(awesome_var=var))
# Sample by pseudo json-path = None
```
AFAIK `var.json.name` it is specific class with own `get` method, which
close to regular nested dict and it is work by the same way as dictionary works
in Jinja Templates, so this behaviour pretty consistent with Jinja
