syntax error, unexpected '??' (T_COALESCE)

[rodion-k]

Hello,

I encountered an issue with the following code:

- $test=['attributes' => ['class' => 'foo']];

p&attributes($test['attributes'] ?? [])

I expected to get:

<p class="foo"></p>

But I actually get:

syntax error, unexpected '??' (T_COALESCE)

Error occurred after the update phug/renderer from dev-master 91b84e0 to 0.4.5. Thanks!

It works fine on https://pug-demo.herokuapp.com/ with both js and php styles.

Thanks, the exact break happens between phug/lexer 0.5.22 and 0.5.23. I will see the changes.

[kylekatarnls]

Hi, lexer 0.5.28 should fix it. Can you retry with all dependencies as last stable?

It works, thanks!
