SCSS silently fails to compile lines beginning with --

[chrisdeeming]

Please see:

This may be as designed but it felt unexpected to me.

When setting CSS variables, if the variable name starts with --, the rest of the line silently skips compilation.

Is this an intentional feature/escape sequence to instruct the compiler to skip the line? I couldn't find it stated anywhere as being intentional.

Found the documentation now:

Interpolation is the solution!
