import { type default as Potato } from 'somewhere';

Configuration

N/A: this shows up even in the REPL.

Current and expected behavior

Current behavior: Babel errors on this, with the following output:

> 1 | import { type default as Potato } from 'somewhere';
    |               ^

Expected behavior: this should parse! See this TS playground for an example.

Note that this is specific to the type default as Binding form: using import { type namedExport } from 'somewhere' parses fine, even if and as you stack multiple of those, including along with named value imports.

Environment

Babel version: 7.17.11 (reproducible anywhere)

Possible solution

Looks like this "just" needs to update the parser to understand that this is valid syntax as of TypeScript 4.5.
