I think the issue has already come up [here](https://github.com/JuliaLang/julia/issues/3427) and the discussion [here](https://github.com/JuliaLang/julia/issues/1470) is also related. As others have mentioned, this should be possible in v0.4 but isn't possible in v0.3.x. Personally, on v0.3 at the moment, if I want to use a type alias as a constructor, I just add a "C" to the end, e.g. given type alias "MyTypeAlias", I define the outer constructor "MyTypeAliasC". I'll be ditching the "C" once v0.4 stable is released...
