/**
* Determine information about this named import or named export specifier.
*
* This syntax is the `a` from statements like these:
* import {A} from "./foo";
* export {A};
* export {A} from "./foo";
*
* As it turns out, we can exactly characterize the syntax meaning by simply
* counting the number of tokens, which can be from 1 to 4:
* {A}
* {type A}
* {A as B}
* {type A as B}
*
* In the type case, we never actually need the names in practice, so don't get
* them.
*
* TODO: There's some redundancy with the type detection here and the isType
* flag that's already present on tokens in TS mode. This function could
* potentially be simplified and/or pushed to the call sites to avoid the object
* allocation.
