To be candid, I had to get out the JavaScript manual and read up on "lexical closures".  I wasn't familiar with the term.  And even after reading, I didn't fully understand it.  But there appear to be some similarities between the examples in the book and my code.

In the case of the component I was writing to build DOM tables dynamically:

var tb = new Table('tb');

creates a new instance of a Table object.  And Table is a actually a Function object which contains other functions (or methods, if you prefer).  And I use code like the following to dynamically add rows to the table:

tb.insertRowBottom(r);

Yeah,  sounds messy.  I'd like to steer clear of circular references.
