That is true of all objects of all properties.

Consider the list I included in my reply to Ali, and spend some time 
experimenting.  LC's associative arrays are very powerful and very 
flexible.  With union and intersect, even more so.  All sorts of rapid 
object styling, replication, serializing for transport, and so much more 
becomes trivial and fun.


Sure, I could write my own functions to do this.  And if I'm the only 
one who's interested it wouldn't take me long.

But the ease and power of this way of working with "the properties" has 
become second nature to me because many years ago Kevin had the insight 
to request that array from the then-engine-maintainer.  If he hadn't 
asked for that, I might still be stuck in the ancient xTalk way of doing 
these things, manually maintaining lists of properties and slavishly 
applying them one at a time in line after line of long blocks of code.

So I'm good either way.  I'm just thinking about the next generation of 
LiveCode scripters.

If we abandon "the properties" as the universal array representation for 
all types, we either lose the value of that function by making it into a 
"sometimes" thing, or reduce the value of widgets by not treating them 
as "real" objects.
