private static Expression doParseExpression(String expression, boolean allowEscape) {
    // should have no function tokens
    for (int i = 0; i < expression.length(); i++) {
        SimpleToken token = SimpleTokenizer.nextToken(expression, i, allowEscape, TokenType.functionStart, TokenType.functionEnd);
        if (token.getType().getType() == TokenType.functionStart || token.getType().getType() == TokenType.functionEnd) {
            return null;
        }
    }
    // okay there is no function tokens, then try to parse it as a simple function expression
    SimpleToken token = new SimpleToken(new SimpleTokenType(TokenType.functionStart, expression), 0);
    SimpleFunctionExpression function = new SimpleFunctionExpression(token);
    function.addText(expression);
    return function.createExpression(expression, false);
