[Zope] Converting REQUEST style lists into real lists

[Tomek Giela]

When you put into your form:

<input type="checkbox" name="varia" value="1">
<input type="checkbox" name="varia" value="2">
<input type="checkbox" name="varia" value="3">
<input type="checkbox" name="varia" value="4">
<input type="checkbox" name="varia" value="5">
<input type="checkbox" name="varia" value="6">

and then select first three of them and submit that form, 
you'll get in form "action" document:

<dtml-var varia>

displayed as: ['1','2','3']

Is there an easy way to convert 'varia' into a list?

Those inputs are dynamicaly generated from database, and I want to analyse
which were choosen in <dtml-in "varia"> block.

Or, maybe there is another trick to colect&analyse them in a simple loop?
