Very cool - thank you MG. No, I sure don't yet know the finer points such
as that which you mention. I think I've blindly adopted code examples from
Groovy scripts out on the internet that are similar, often not really
understanding. I still have so much to learn about Groovy. As best as I can
tell so far, Groovy appears to be java based, with refinements and
enhancements.
One thing I've been thinking about recently is whether these refinements
always make things easier to read and maintain, or more cryptic and
difficult? Some groovy things I've seen sometimes make it a little more
difficult to unwrap what the code is doing. But as I said, I suspect that's
more a function of my lack of experience rather than a Groovy problem.
This users group is very helpful. Thank you all again.
Cheers,
Jim
