cannot evalute mixin(uuid("bla")) at compile time

[Sam Hu]

Base on D1:
interface IADsPropertyEntry : IDispatch {   
  mixin(uuid("05792c8e-941f-11d0-8529-00c04fd8d503"));   
  ...  
Error when compile:
argument to mixin must be a string,not 
mixin(uuid("05792c8e-941f-11d0-8529-00c04fd8d503"))   
cannot evaluate uuid("05792c8e-941f-11d0-8529-00c04fd8d503") at compile time  

What's the problem and how to solve it?Thanks for your help in advance.
