Would a Lua port use System XML? I suspect not - which is what it might take to make XML processing "for the masses" on z/OS.

I think YASL is the term your looking for Wayne. Having said that, how many scripting languages do we have on z/OS? REXX, CLIST, perl or propriety vendor languages like NCL etc. How many of them can do mundane tasks like parsing XML? That's easy in Lua http://matthewwild.co.uk/projects/luaexpat/examples.html. How would you parse XML? Code a COBOL/PL/1 program. Use XML system services in assembler. Use C++ xereces. None of those solutions are simple. If you wanted to write a quick web app would you choose WebSphere Java, CICS? Yet again piece of cake in Lua http://www.keplerproject.org/ or the bleeding edge Luvit framework which is a node.js clone, already in production at rackspace http://luvit.io/.

The cupboard is pretty bare other than JVM languages which don't run in the native environment. Most people consider mainframe modernisation to be replacing green screens with GUI front ends. That's all well and good but what I really yearn for are the tools that I'm used to on other platforms. I chose Lua because its easy to port and I was already using it to create cross platform mobile apps with the corona SDK. The z/OS ports of python and perl are stale.

Although Lua is well known as a video game language and notorious for the flame/stuxnet viruses it runs brilliantly on z/OS.
