This is a "common" complaint, and ver 0.4 will have a fix for this. 
(Actually, I just committed it to CVS)

Basically, I think what I'm going to go with is:

if you end a script block with " $%> ", then PSP will pick up the amount
of indentation that the last script line was using, and add it to the
indentation level.  That level of indentation will exist until the next
script block.
This is IN ADDITION to the auto indentation that comes from ending a
script block wth a ":". The auto indentation still has to be ended with
a <% end %>, but, that <% end %>, because it is a script block, will
also end the $%> indentation level.

So your code would look like this:
-------------------------------------------

<%@ page method="writeHTML" %>

PSP Test

<% q=0 %> 
<% 
if q: 
	self.writeln("We have Q")
else: 
	for i in range(10):$%>
Sorry! No Q !!!
<% end %> 
-------------------------------------------------

How does that strike you?

I'm the one who will make that argument (for a Can or Servlet).  BUt the
blocks are so common and necessary that they are a special case.  I
think the solution above will work well.

About like putting a round peg in a square hole. It "fits", it works, but
there is still, to me, a basic problem here. Aside from the question of
exactly which block did I end with "<% end %>", the "$" has a really krufty
un-pythonic feel. I realize that perhaps this is a necessary evil in this
scheme but when I sit down to code a PSP page I feel like I am catering too
much to the language instead of it to me. I am currently a JSP coder so
maybe I'm the square peg myself but when I create a JSP or look at one
created by one of my co-workers, all I have are <% %> and <%= %>  and
blocks made with braces. I would be very afraid to work with others on a
PSP-based project where tabs and spaces and significant and insignificant
indentation would all mix together into a morass of confusion. I'm not so
sure I'm smart enough to keep them straight just by myself.

I realize this is just a load of subjectivity, and I'm not really offering
much in the way of a solution, but I feel that this sort of thing will be a
barrier to the widespread adoption that will be require to perpetuate
Webware. Webware as a whole is looking up as an excellent product, but it
needs a good HTML display solution.  Ok it has an excellent one in PSP, but
it just needs to go that extra kilometer.

Ok, I will offer a potential solution: { } . They really could work.
