I have the followong TAL-expression:
<td
    tal:content="structure python:here.test(myImportantCondition and
myExpensiveMethod(), myExpensiveMethod(),
'myDefaultString')">myDefaultString</td>
The safe way looks like:
<... tal:define="myRes python:myCond and myMethod()"
         tal:content="python:test(myCond,myRes,default)"
	 ...

When you know that "myMethod()" cannot return a Python false
value, you can use

         ...
	 tal:content="python myCond and myMethod() or default"
	 ...
