Actually, I believe this is because dtml-let is
setting up another namespace. Your original "uglier"
version works, though:

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('counter', 1)">
<p><dtml-var counter></p>
<dtml-in "_.range(0,10)">
<dtml-call "REQUEST.set('counter', counter+1)">
<p><dtml-var counter></p>
</dtml-in>
<dtml-var standard_html_footer>
