{% use %} does not support dynamic templates (it cannot be a variable either, it has to be a string)

[syrm]

Hum ? Why not ?
The documentation said :
Even if you will probably always use the template_from_string function
with the include tag, you can use it with any tag or function that
takes a template as an argument (like the embed or extends tags).

[stof]

But use does not take a template as argument. It takes a static template name. It cannot be dynamic. There is no dynamic use

[syrm]

The documentation said use take a template argument.

[stof]

Here is the message I see in the doc of the use tag:

Because use statements are resolved independently of the context passed to the template,
the template reference cannot be an expression.

[syrm]

Ok, that's annoying.

closing. this might be possible in Twig 2.0 though.

I'm using Twig 3.3 in Symfony 5.2.3, it's still not possible. :(
