Template syntax error

[joshuakb2]

This is similar to issue #2719

1. Describe your issue:

Not all JavaScript expressions work in a template expression. This is unexpected particularly because the documentation says in the Syntax section:

All template expressions are "just javascript."

2. Can you reproduce the issue?

Here's an example using valid JavaScript that causes a syntax error:

<div>{ ['Hello', 'world!'].join(' ') }</div>

3. On which browser/OS does the issue appear?

Chrome, but I'm assuming everywhere.

4. Which version of Riot does it affect?

Riot 4.0.3.

5. How would you tag this issue?

It seems like either the documentation should be improved, or templates should support all valid JavaScript syntax.

Thank you, it was a compiler issue. It got fixed in Riot.js@4.12.4
