Thanks for the link George, It was interesting.

I think some sort of inline or deferred local statement would be useful 
also.  It would serve as a limited lambda (after it's removed), eval 
alternative, and as a inlined function in some situations as well I think.

Something like:

     name = defer <expression>

then used as:

     result = name()

The expression name() will never have arguments as it's meant to 
reference it's variables as locals and probably will be replaced 
directly with names's byte code contents at compile time.

Defer could be shortened to def I suppose, but I think defer would be 
clearer.  Anyway, it's only a wish list item for now.

Regards,
Ron
