On that note, it would be useful to have some way of accessing control flow information too. palantir/tslint#2038 (comment)
Related to #11728
I'd also like have this exposed for danvk/typings-checker#15
Would be resolved by #9943.

Could
isTypeAssignableTobe exposed on the type-checker for use by API consumers? This would be helpful for analyzing code using type information. I would like to checkinstanceofexpressions for assignability in a lint rule (palantir/tslint#2046).getBaseConstraintOfTypewould also be useful for doing checks inside generic functions.isTypeAssignableTowould also be useful for ano-unnecessary-castrule.
