All right! I'm missing something! Except for the second example, I don't
quite understand the other examples and I can't see a reference to
semicolons in TALES. I tried the third example in tal:repeat and it didn't
work out. Could you enlighten me?

== running this script ==
## Script (Python) Semicolon

return context.usesemicolon(a='ola', b=' mundo')

== with this in a Page template called usesemicolon ==
 <li tal:repeat="item options/a;b">
     <span tal:content="item"> item value </span>
 </li>

== gives the error ==
An error was encountered while publishing this resource.

Error Type: KeyError
Error Value: a;b
