I've heard your reasoning and it doesn't satisfy me nor many people whom I
have discussions with outside of this list. Say it as much as you want, but
these are not variables. They are different -- they are a new class of
things.

And I'm not satisfied with this reasoning. Lots of people are not. Just
because variables cascade doesn't make them properties. If they were
properties, then properties could be read like variables without any issue.

"Fetishize"? Come on, Let's avoid the loaded language.

I read a lot of words, but I'm not sure you said anything in this
paragraph. So I don't know how to respond. I don't see any point in arguing
about language design philosophy in this thread.

Here's why I don't like the property syntax: It gives fine structure to an
identifier where there needn't be any. the delineation between declaring
something is a variable and the name of that variable should be syntax, not
a naming convention.

If it really is a property then make it a property with a -user- prefix and
then make all properties accessible for read. This is a lovely system. it's
not variables really. but it is completely consistent. If your going to
draw a line about what properties can be read as a value, then make this
delineation formal.
