The string variables "extra features" patch (#1043790)
only contains two features right now:

1) String variables are auto-promoted to numbers if they are
   encountered during evaluation of an arithmetic expression.
   e.g:   (3 == "1" + "2")  evaluates to TRUE

2) Integers are auto-promoted to strings if they are encountered
   during evaluation of a string expression.
   e.g.:   
	N = N + 1
	filename = "run_" . N . ".dat"
	print filename
		run_4.dat

I am not aware of any problems introduced by either feature,
but comments are welcome.
