I am having trouble with using OrderedMap(someArray) in typescript. Typical errors are like:

 Overload 1 of 2, '(collection?: Iterable<[string, number]> | undefined): OrderedMap<string, number>', gave the following error.
        Argument of type '(string | number)[][]' is not assignable to parameter of type 'Iterable<[string, number]>'.

This types of problems are valid for all arrays I tried, including Array<Array>.
While working in pure JS and sometimes with typescript in the browser it provides type errors for typescript on nodejs because OrderedMap does not have an overload for arrays. Please, improve type-script types in immutable js!
