<br>
With the new `Data.Typeable` and `Data.Reflection` in base 4.10 have we really lost the ability for users to compose `TypeRep`’s?<br>
<br>
I was using `Data.Typeable` before (mainly `mkTyConApp`). But in the new base 4.10 I cannot find any way to achieve the same goal.<br>
I have read the wiki page Typeable and Typeable/BenGamari and neither explicitly mentions the removal of `mkTyConApp` and similar facilities. In fact the latter mentions potential implementations for user constructed type applications twice with `mkTrApp` at the beginning of the page and `mkApp` at the end.<br>
Furthermore the documentation for `Typeable` (and `Reflection`) also never mentions the fact that this functionality was removed.<br>
<br>
My question is this: Is this intentional? Is there now a consensus that there should not be user constructed types? Or is there some subtile issue that I’m missing wich prevents user constructed types for now or always?<br>
<br>
Thanks in advance guys.<br>
<br>
Best regards.<br>
