The more I think about this, the more serious of a bug it appears.

Consider the innocuous,

     put "stack " and the short name of this stack into myStack

This will produce something like

     stack someStack

And then later

      open myStack

This is a rather drastic change in how LiveCode works.  For decades,


    open aString

would take that string, if a single item such as a variable, as a literal.
That is apparently no longer the case; the unquoted words of aString, such
as whatever the value of "myStack" is, are now apparently being processed
*again*.

This breaks code, and there is no reason to expect an arbitrarily named
variable to even *be* around.

On top of that, when there is no variable of a name, the word is supposed
to be processed as string; this has been the case since hypercard.

While I am quite aware of the value of being able to point one variable at
another, this is just half-cocked (and would be even if it wasn't breaking
defined behavior.


And this is breaking production code I use on a daily basis.

*Bug 13972* <http://quality.runrev.com/show_bug.cgi?id=13972> - open card
treats string as variable breaking old code (edit
