**I'm submitting a ...** (check one with "x") ``` [x] feature request ``` **Current behavior** The metadata collector reports unsupported syntax form for interpolation strings. **Expected behavior** Interpolations strings should be handled like string concatenation. **Minimal reproduction of the problem with instructions** Incllude an interpolation string in an exported symbol, such as: ``` `${foo}/${bar}` ``` **What is the motivation / use case for changing the behavior?** Better support for the full syntax supported by TypeScript.
