how could I identity if a Type is a composite type, i.e., something that could be `getfield()` ? e.g. by a `isstruct()` function?  
thanks.

oh, sorry for the post. The answer is: `Base.isstructtype()`

btw, I think a better string matching algorithm could be employed as I searched [“isstruct” in docs.julialang.org](https://docs.julialang.org/en/v1.4/search/?q=isstruct) but it does **not** show up anything about `isstructtype()`.
