Missing variable in documentation for "mix()"

[rjelte]

On lesscss.org, the following line explains the use of the mix function:

mix(@color1, @Color2); // return a mix of @color1 and @Color2

However, mix requires a 3rd parameter, a percentage, like follows:
mix(@color1, @Color2, 50%); // return a mix of @color1 and @Color2

+1 came here to report the same issue.... I think LESS is awesome... however I wasted over an hour manually calculating the right hex colors .... because the documentation was missing the %.

Please update this and prefend other people from wasting their time! :-)
