I&#39;ve been using Gambit Scheme as my primary language for about a <br>year  now, and I&#39;m finding it pretty much the best for what <br>I&#39;m doing.  However, the one thing that I find lacking is read- <br>macros:  Why doesn&#39;t Scheme have an equivalent to CL&#39;s set-macro-char 
<br>and the like?  It seems to me that you can do lots of interesting <br>things with them that you couldn&#39;t do otherwise.<br><br>Does anyone know of a way to do something equivalent to&nbsp;the&nbsp;following&nbsp;CL&nbsp;in&nbsp;Gambit?&nbsp;&nbsp;I&nbsp;suspect&nbsp;that&nbsp;there&#39;s&nbsp;some&nbsp;way&nbsp;to&nbsp;do&nbsp;it&nbsp;using&nbsp;readtables...but&nbsp;I&nbsp;have&nbsp;no&nbsp;idea&nbsp;how..
<br> <br>(set-macro-character #\] (get-macro-character #\))) <br><br>(set-dispatch-macro-character #\# #\[ <br>  #&#39;(lambda (stream char1 char2) <br>      (let ((accum nil) <br>            (pair (read-delimited-list #\] stream t))) 
<br>        (do ((i (ceiling (car pair)) (1+ i))) <br>            ((&gt; i (floor (cadr pair))) <br>             (list &#39;quote (nreverse accum))) <br>          (push i accum)))))<br><br>Thanks for your time,&nbsp;any&nbsp;help&nbsp;is&nbsp;appreciated!
