Hi,
Currently FallBackIfEmpty has the following signature:
public static IEnumerable<T> FallbackIfEmpty<T>(
this IEnumerable<T> source,
T fallback)Does it mean if T is a method call private static T CreateDefault() it would be called anyway, even if source is not empty? I think yes, it would be.
So I propose to add an overload:
public static IEnumerable<T> FallbackIfEmpty<T>(
this IEnumerable<T> source,
Func<T> fallbackFactory)which would call it if only source is indeed empty.
Are you willing to accept a pr from me once agreed on the principles. Thanks!
