Details:

I was trying the new Variable Editor and I used


y = 1:10
openvar (y)


There were two warning messages issued immediately in the Command Window.


warning: implicit conversion from matrix to sq_string
warning: implicit conversion from range to sq_string


In addition, the Variable Editor did pop open a tab with a crazy string for
the variable name which it said it could not find.

The correct syntax should have been


openvar ("y")


where "y" is a string.  Instead, I got something like


openvar (char (y))


I understand how this happened, but it would be nicer if the openvar function
would validate its inputs just a bit.
