Somehow, emulating the above doesn't attract me nearly as much as it
evidently does you. What happens in cases where the parser is unable
to infer a data type, or infers the wrong one? Or even if it does
infer a type, how do you find out what it inferred? I'm not excited
about building a capability that fails to address any except the simplest
use case.
