English Like?

I agree that LiveCode script should become more English like as time goes on
not only with english words but also with more natural(or intuitive)
grammar.

>From your examples I think it would be more natural to type.

   put the third index of tNumericArray into tFoo

OR

    put the backColor of control "foo" into tVarBackColor

(in this example have the engine know it has to get the long id of control
"foo" to access the backColor than for the programmer to remember to assign
it first.)

Often when I am typing a script and I am not sure how to do it I wing it
first to see if what I intuitively write will work.   If that fails then go
to the dictionary or then forums.   

One example is the following.

I wanted a button in a group to access a property of the group so I typed.

   put the width of this group into tWidth.

When I apply that in the script editor it shows no errors but when I run it
it stops with the following error:

 (Chunk: can't find background)

The above line would work if I used card or stack instead of group.  In this
case I had to put.

   put the width of the owner of me into tWidth

So that is grammatically English but not the way I intuitively thought of it
and the sentence is a little unnatural.

I can fake a more natural sentence using a function to hide the way of
accessing the group to get it to read better.

   put the width of this_Group() into tGroupWidth

   function this_Group
      return the owner of me
   end this_Group

It would be nice if this is the direction of the language.

My nickel's* worth.  

* in Canada we ditched the penny a couple of years ago so every purchase is
rounded to the nearest nickel. :-)
