[Mono-dev] Suggestions on the library implementation

[code]

Could part of Mono library goes beyond .NET 2.0? For example, HashSet is
.NET Framework 3.5 class. However, it seems there is no obstacle that could
prevent it from being implement in Mono 1.2 series. 

The implementation of some classes, such as HashSet, is not dependent on
specific OS feature or hardware architecture and is very useful. Could these
classes be implemented earlier? 

Thanks!
