There was a problem hiding this comment.
The standard Linq methods are already eager for these two. These differ from Linq
- in their handling of null (no exception)
- Average() returning NaN instead of throwing. (though there are Linq overloads that takes enumerables of nullables, and if the enumerable has no nonnull values (empty enumerable is a degenerate case of this) returns
null) - calling
Count()rather than counting during theforeach- if the enumerable is a List this won't matter, but for others it could enumerate twice - Linq uses checked arithmetic

Renamed GoodLinq to EagerLinq and added it as a part of the System.Linq namespace as an extension method.
