Digit-only names are excluded #40
Description
The npm registry includes several packages whose names consist only of digits. Examples:
The filtering was introduced in #9, stating as reasons
because they're probably all bunk, and things get screwy in JavaScript when you try use one of these package names as an object key
Neither of these seems valid to me. The first package I listed above has reasonable weekly download numbers, and all these names are still strings which makes them valid object keys.
