Infact, - "#{}" is not a valid pug code: an interpolation should not be empty, and if it's not an interpolation, you must escape it:

- $a = "\#{}"
=$a

[rodion-k]

I thought interpolation shouldn't work in code. Seems in pugjs it does not work

-
  var name = 'value';
  var a = '#{name}';
= a

gives #{name}

Yes, it's what we discussed with @TorbenKoehn I try to know why the engine do so and if it's a regression.

Hi @rodion-k please run composer update and tell me if it fixes your problem. Now code elements are no longer considered as interpolable.
