------------------------------------
Hi Richard,
Some comments about PIG-1479_3.patch:
* The ScriptEngine implementations that can be used are still hardwired. As a
user I would want to add a parameter to the command line to use my own (adding
it to the classpath and providing the class name). For example I'm working on a
javascript implementation for Pig-Greek. Currently I have no way of using it
without modifying Pig's code.
* I like to not have to define a main() function for the top level code,
however using regular expressions to separate functions from the main code
seems at high risk of not working in many cases (in
JythonScriptEngine.getFunctions(InputStream)). It would be better to trust an
actual Python parser or to leave it as is: requiring a main() function.
