K, if you move the "outer" "someFunc" into its own mixin template, like such:

mixin template otherInnerMixin() {

  void someFunc( string s )() if( s == "toto" ) {

  }

}

and change "outerMixin" for this:

mixin template outerMixin() {

  mixin innerMixin;
  mixin otherInnerMixin;

}

Then it works.
