Using variables as snippet name in render tags

Hi!

It seems pretty unreasonable (as an outsider) that I can't do this:

{% assign my_template = 'my-template' %}
{% render my_template %}

I can't understand why render should care if the string it uses is inline or from a variable, so long as its a string.

This feature would be useful for rendering partials based on things that need to be dynamic (For example rendering a different partial if a user was logged in or out) or when you want to make components more generic.

For example, say I have a bunch of svg icons as .liquid files. I want to render them, wrapped with some markup. Rather than edit each icon with repetitive wrapping HTML, I want to create an adapter component and pass in the icon name so I could write:

{% render 'icon', icon_partial: 'cart', text: 'View cart' %}

And then inside snippets/icon.liquid

<div class="icon">
{% render icon_partial %}
{{ text }}
</div>  

Am I being dense? This feels like a step back from include tags.

Cheers

Start by examining the render tag and comparing its behavior with the include tags discussed in the issue. Use the snippets/icon.liquid example to trace how a variable such as icon_partial would be resolved. Done means render accepts a variable snippet name while preserving the demonstrated wrapper and argument behavior.
