I’m still working on getting ADVANCED OPTIMISATIONS working with the SDK +
Flash Player + application JS combo. However, with SIMPLE OPTIMISATIONS,
which includes all code and the kitchen sink - it’s basically whitespace
removal, it doesn’t recompile the JS - the output file is a whopping 2 Mb!
Cool, huh ;-) I expect some serious reduction in file size when the GCC is
able to actually parse an entire application and optimise the code properly
… We’ll see.

FalconJX should properly parse this construct. That will be challenging
though, as we’d need to look forward in the AST and then handle these
multiple catch blocks and turn them into a proper set of ‘if … then’
statement in a single catch block.

Also, how “heavy” is this problem?  Are the catch nodes children of the

Actually, hoping to get a blessing for rewriting the SDK, I didn’t look at
the AST at all :-)
