On a stylistic tangent: combining "nocall" with "python" doesn't make
any sense, and I don't believe it has any effect. Nocall's purpose is
to prevent implicitly calling the object traversed at the end of a
*path* expression.

Also, don't use tal:content when you don't actually want to insert the
result of the expression. The most common idiom I've seen when calling
something purely for side effects is to abuse tal:define:

<span tal:define="dummy python:request.response.setHeader(...)" 
      tal:omit-tag="" />

Or, better, put the define in a tag that actually serves a purpose and
you can leave out the omit-tag as well:

<head tal:define="dummy python:...">
