&gt; big memory leak ... two parsers in sequence<br><br>A related question, are these two equivalents?<br><br>foldl2 f g y z lst = (foldl f y lst, foldl g z lst)<br>foldl2' f g y z lst = foldl (\(i, j) x -&gt; (f i x, g j x)) (y, z) lst
<p class="MsoNormal">If no, is there some strictness that can be added to make them
equivalent?<span style="">&nbsp; </span>And if so, could a compiler
make this optimization as to avoid these sorts of space leaks?<br><br>Thanks,<br>Greg<span style="font-size: 10pt; font-family: Arial;"></span></p>
