Cannot modify individual list or dict item using set

[TheWebTech]

Code explains better than words could.

{% set items = ["item1","item2"] %}
{% set items[0] = "new value" %}
expected behavior: {{items}} = ["new value","item2"]
actual behavior: {{items}} = ["item1","item2"]

We have list functions, but none seem to recreate the same sort of simple functionality that many programming languages support.

One possible workaround for developers would be to do {% set items = ["new value"] + items[1:] %}

We could support setItem on Pylist. So this would look like {% do items.setItem(0, "new value") %}. There isn't supported directly in Jinja2 though.

{% do items.set(0, "new value") %} should work actually
