&--classname causes error

[grobitto]

.class1 { &--class2 { background:white; } } should produce .class1--class2 { background:white}, but gives an error instead. Looks like it has something to do with html comments in less4j grammar.

the .parent--child classnames are quite common in BEM notation

Thank you, that seems like parser error.

what about solving this issue? I'm going to move compilation to less4j, but this issue stop me
