Subj : Adding 'goto' statement to Rhino

Hi,

The company I give blood to :) is in the process of revamping most of
there core technology, which currently includes a less-than-stellar
proprietary scripting language.  I have successfully made the case
that Rhino can serve as a replacement for the in-house language as
well as provide the company with many additional benefits.

However, since we have many scripts written in the in-house language,
a conversion process is being put together which will parse the old
scripts and write them out in JavaScript.  (Obviously there is more to
it than that, but work with me here)

Unfortunately, 'goto' statements are used excessively in the scripts. 
Therefore, for the conversion to work I have to add 'goto' & 'label'
statement support to Rhino.

So I opened up the Rhino code, but before I go any further I just
wanted to get some input from the group:

1. Has this already been done by someone? If so are the changes
available somewhere?

2. Since there is already support for loop labels and break's with
labels such as [restart: while(true) break restart;], could I simple
piggy-back on the interals of this?

3. What files/areas should I be looking to make such a change in?

4. Is there any pitfalls that I should know about?

Thanks for any help,

-Josh <G>
