Probably missing forward declaration for mixins

[sequilox]

This is about Bulma.

I am not quite sure if this is a bug or a feature (i.e. done on purpose).

Overview of the problem

I'm using Bulma 1.0.0
This is a Sass issue: I'm using version [1.0.0]
I am sure this issue is not a duplicate

Description

If I only include the main Bulma file (@use bulma/sass/_index.scss), I cannot use mixins like the following:

@include mixins.until(451px)
    font-size: 75%

Steps to Reproduce

Create your own sample.sass file and use a Bulma mixin:

@use bulma/sass/_index.scss

.sample
    @include mixins.until(451px)
        font-size: 75%

Expected behavior

It works, i.e., the corresponding CSS is compiled.

Actual behavior

 Error: Undefined mixin.
    ╷
   │ ┌     @include mixins.until(451px)
   │ └         font-size: 75%
    ╵

Workaround

Create your own sample.sass file and use a Bulma mixin:

@use bulma/sass/_index.scss
@use bulma/sass/utilities/mixins.scss

.sample
    @include mixins.until(451px)
        font-size: 75%

Solution

Actual Forwarding Chain

bulma/sass/_index.scss --> bulma/sass/utilities/_index.scss -///-> bulma/sass/utilities/mixins.scss

Expected Forwarding Chain

bulma/sass/_index.scss --> bulma/sass/utilities/_index.scss --> bulma/sass/utilities/mixins.scss

Maybe there is some good reason for it, but I would forward mixins.scss inside bulma/sass/utilities/_index.scss:

@forward "mixins"
