analysis of export all throws error when path is a directory

[grahamdyson]

When the module path of export all is a directory an error is thrown and the process terminates:

export * from "directory";

Error: EISDIR: illegal operation on a directory, read

This scenario shouldn't terminate the process, this is the same behaviour as when a file doesn't exist. The directory should also be checked for an index file to support Node.js/CommonJS module resolution.
