<div dir="ltr">Reading through Ragel guide, I see examples like this one:<div><br></div><div><div># Match a word followed by a newline. Execute A when</div><div># finishing the word.</div><div>main :=<b> <font size="4">(</font></b> lower+ %A <b><font size="4">)</font></b> . '\n';</div>
</div><div><br></div><div style>Question I have is: why is grouping used here ? Could this be written simply as</div><div style><br></div><div style>main :=<b> </b> lower+ %A . '\n';<br></div><div style><br></div>
<div style>And if not, what would be the difference ? </div><div><br></div></div>
