How hard would it be to swap out the JS engine in Komodo with one of a 
newer vintage (i.e. off the Gecko 1.9 branch)?  Lately I've been using a 
feature of JS 1.8 (expression closures 
<http://developer.mozilla.org/en/docs/New_in_JavaScript_1.8#Expression_closures> ) 
that the syntax checker thinks is a syntax error.

Would it be feasible for me to build a newer version of the engine and 
replace the one in Komodo with it?
