Variable variable names

[reggi]

Can we please get a way to create variables with variable names :)

{% assign myVar = "hello" %}
{% assign [myVar] = "hello2" %}
{{ hello }} <!-- hello2 -->

or

{% assign myVar = "hello" %}
{% assign global[myVar] = "hello2" %}
{{ hello }} <!-- hello2 -->

or create objects :) or append to existing objects :)

{% assign shop.hello = "win" %}
{{ shop.hello }}

and

{% assign shop["hello"] = "win" %}
{{ shop["hello"] }}
