Please be careful with attributions; "fundamentally ineffecient" was David, not
me. I was questioning his claim.
OOREXX does seem to be less efficient than SAA ("classic") REXX, but I use it
regardless because of its expressive power. I know of no barrier to a more
efficient design, nor do I know of any fundamental difference between NetRexx
and oorexx that would prevent one from being efficient but not the other.
Not oorexx, but IBM has used REXX as the implementation language for, e.g.,
some CMS commands. I don't recall those commands being too slow.

No, for what ooRexx does and allows for it is not „fundamentally inefficient“.
If forgoing all its helpful new features, because all of a sudden „inheritance“
or „message paradigm“ is not important, then you could implement it totally
different. But then you loose what makes it so powerful and easy to use.
Just think about REXX and for what purposes you use it there. If „hi speed“
gets important then you probably use native code/functions/libraries from REXX.
I know of companies that use ooRexx with BSF4ooRexx for nifty professional
applications, where they use powerful JavaFX for the GUI, but interact with
RDBMS on IBM middle range hardware. They develop on the MacOS platform, but can
deploy their products on Windows and Linux. Complex, challenging applications
that get created and maintained with ooRexx+BSF4ooRexx.
The reason? They had REXX knowledge (coming from the mainframe world, also
consulting AS/400 customrs etc.), learned about ooRexx and BSF4ooRexx and were
able (on their own!) to learn and research all they needed for a solution that
others would have thought was impossible with REXX knowledge. Rather they would
speculate/expect to have to learn a new language from scratch. This is not the
case, one can keep and take advantage of the REXX knowledge and year long
experiences.
