@apply() Custom CSS Mixin fails LESS Parse

[mflorence99]

Apologies if this is the wrong place to ask:

I tried to use the @apply() syntax as documented here.

I am building stylesheets in LESS v3.

The @apply() causes the LESS preprocessor to choke.

Does anyone have a work around for this? Many thanks!

Sass supports custom at-rules.
Although you have to compile with ruby, libsass doesn't support them yet.
sass/libsass#1263

Many thanks for that suggestion! Let me close this issue and express in another what I found.
