On the other hand, the further down we push the error checks, the worse the error messages for our users. Due to how bad template error messages still are, this is one of the largest problems we have today. The dynamic matchers will hopefully get some of that out of the way, but I still believe that for now we just want to spell out all the types it's callable on.
Do you have a such a list?
