LESS attribute from variable reports warnings.

.someclass {
    @some-data-attribute: ~"data-something"; 
    
    &[@{some-data-attribute}] {
        color: red;
    }
}

LESS Plugin for Eclipse shows error:

Multiple markers at this line
- no viable alternative at input '@' 
- mismatched input ']' expecting '}'
- no viable alternative at input ''

This is valid less code. It compiles correctly during ant build, and tested with an online less/css compiler.
