{
lexer.Whitespace(state.RuntimeState);
int start = lexer.Position;
state.RuntimeState.Runtime.ParseTrace.Enter(this, lexer.CurrentSource(), range.ToString());
char character = lexer.Peek();
if (!range.Contains(character))
{
lexer.ErrorStrings[start].Add(range.ToString());
state.RuntimeState.Runtime.ParseTrace.No(this,
lexer.SourceFrom(start), TextEscape.Quote(character));
return ParseTree.No;
}
lexer.Read();
