I have used this.  This is better than my call-return trick.  I had 
tried the trick to see if it would avoid a limitation and forgot to go 
back.

Both get the right "me".

However, both have the same limitation.  Without a lot of work, they 
both are limited to simple constant parameters.  As soon as I use a 
variable as a parameter to the function, I have problems.  This works:

   put value("myFunction(23)", stack "My Stack") into myValue

This does not:

   put complicatedString() into alpha
   put value("myFunction(alpha)", stack "My Stack") into myValue

Is there a way to pass general parameters?
