Error on compiling .less on 2.0.2-wip

[netatoo]

Hello,

For a few hours since the last pull I made on the branch 2.0.2-wip, I am unable to compile the .less files.

On CodeKit I get the following error:

NameError: #grid > .core is undefined in /Users/netatoo/github/bootstrap/less/responsive.less:203:2
202   // Fixed grid
203   #grid > .core(40px, 20px);
204 �[0m

On Less Mac App, he told me that the error comes from mixins.less, line 504:

.spanX (@index) when (@index > 0) {
      (~".span@{index}") { .span(@index); }  
      .spanX(@index - 1);
}

Thank you in advance for your help

I believe the error is still present in Less 1.3.0: #2516 (comment)
