Is it possible to support nested expression parsing? #14

Is it possible to support nested expression parsing like this: lambdaParser.Parse("(List<string> list) => list.Where(o => !string.IsNullOrEmpty(o))");

VitaliyMF commented 6 years ago

LambdaParser cannot evaluate expressions like that. Usually LambdaParser is used for expressions that can be entered by the user - like formulas or custom conditions. As for me, ability to define nested lambdas is overkill, as you always provide 'helper' functions that can be used in the expression like "List.RemoveEmptyEntries(list)".

Got it, thanks.
