In the Q for Mortals section on contexts (http://code.kx.com/wiki/JB:QforMortals2/workspace_organization#Contexts), it shows that one is able to retrieve variables from the default context by accessing the context dictionary:
q)\d .new q.new)`.[`ztop]
However, this doesn't seem to work for assignment:
What is the right way to assign to variables in the default context from another context?
