Thanks for the idea. I see a few issues with the example. It
wouldn't handle:
func {
...
stmnt <-nothing to grab this newline
}
It also won't handle several blank (newline terminated) lines in a
row because empty won't consume newlines. Adding "newline" to
statement could cause 2 newlines in a row to be required. But I'll
play with it now that I have something else to try.
Thanks,
