Remarks

Parses Enhanced C# code into a sequence of Loyc trees (LNode), one per top-level statement.

You can use EcsLanguageService.Value with extension method ParsingService.Parse(IParsingService, UString, IMessageSink, ParsingMode, bool) to easily parse a text string (holding zero or more EC# statements) into a Loyc tree. One does not normally use this class directly.
