Howdy, Gabriele:
The new capability of QUERY was mentioned in the last
changes file for view beta 4.1. I figured it was easy
to overlook so I've been hoping to find a good
oportunity to mention it. :-)
x: make object! [a: 1 b: 2]
query/clear x
== none ;- nothing when it's brand new
set in x 'a 33
z: query/clear x
== [a]
reduce z
== [33] ;- block returned bound to the queried object
c: to-set-word 'b
x/:c 99
query/clear x
== [b] ;- even round about modifications are remembered
New strains of REBOL introspection! (-:
