Ah!  Reading the "Could not find value for" thread helped me solve  
the problem.

The 'main' class, which includes all of the code outside of all other  
classes, is evaluated before the node is evaluated, which is why  
you're seeing that behaviour.  You wouldn't get the variable value in  
the 'base' class unless the variable were set in the top-level scope,  
but you're still dealing with an ordering issue.

Looks like I should reverse things and evaluate the node first if  
there is one, so that you don't have that ordering issue.

This whole 'main' class thing keeps getting more complicated, which  
is quite surprising to me.
