There was a problem hiding this comment.
string is valid for number indexing as well.. so symbols aside..
indexrType = (isTypeAssignableToKind(exprType, TypeFlags.NumberLike) && getIndexTypeOfType(parentType, IndexKind.Number) || getIndexTypeOfType(parentType, IndexKind.String)

const named = Symbol("");
let { [named]: prop } = strIndexed;
void prop;``today that is string ... we probably wanna keep it this way until we have a symbol indexer.

@mhegazy updated. Destructuring now has the same buggy behavior as indexing 😿 |

We need to update it to handle symbols like we do in regular indexing. |

@mhegazy Does this look like the correct errors to issue for symbol destructuring (and should they be noImplicitAny)? |
