Greetings<div><br></div><div>I need to parse simple D expressions at compile time. I was wondering if somebody on the list has some example code that could be of help to me.</div><div><br></div><div>I am working on an opensource constraint solver  and expressions that I need to parse can be reasonably complex such as &quot;x + y*n &lt; 32 &amp;&amp; x &gt; 4&quot;. I want to code a string mixin that parses such expressions and writes out code that creates a parse tree for the given expression.</div>
