Topic: Desired string interpolation syntax

Hello :wave:,

I'm currently enjoying exploring roc, and have a quick question about the syntax for string interpolation.

In the docs I'm seeing that the syntax looks like "Hello, ${name}".
In the interactive homepage demo visitors are asked to interpolate with syntax "Hello, $(name)".

I was wondering if both versions will always be supported, and/or if there is a preferred version.

Thanks!

I think $(name) is going away and ${name} will become the only way to do it

I'll update the homepage

Thanks for replying! If you don't get around to it, I'll happily submit a PR later today or tomorrow

Left a tiny comment to avoid blocking the flow of the interactive demo
