According to previous discussion about Sweet expression, we should treat curly-brackets as delimiter, say:<div>{+ 1 1} ==&gt; 2</div><div>This patch added an option to read-option to enable this. And the patch will cause Guile treats curly-brackets as delimiter in default. </div>
<div>We don&#39;t see any harm for this till now. But one may disable it with read-option as will.</div><div><br></div><div>Regards.</div>
