This would be useful without even calling a method.  I've thought a
couple times about:

<a href="a/valid/path" tal:attributes="href
string:${request/BASE1}/${tag/href}">

or

<input type="text" name="foo" tal:attributes="value
python:request.get(tag['name'])">

Of course, these two examples lead directly to the observation that the
TALES expressions are generic, and that you would probably want to apply
them to all tags of a given type.  Something like:

<body tal:process="a fixPaths;input setValues">

...could be implemented by adding implicit TAL code to each 'a' and
'input' tag as it is encountered. Then we have to decide how to handle
the interaction of multiple processors with explicit TAL code, as in:

<div tal:process="table tableMagic;table moreTableMagic">
  <table tal:define="foo expr" tal:condition="some/test"> ...
