Does nim implement predicate dispatch?

[geohuz]

I'm learning the nim and excited to know that it supports multimethod natively! 
And when I learning the concept of multi-method from wikipedia, I saw there is 
a general concept of 'predicate' dispatch which is more generalized, I'm not 
sure if nim has this? Is the "concept" of nim can be used for prediate 
dispatch? Hope somebody can help with this question with code sample. Thanks!
