^^^ Yup!  This is what I was suggesting in my last email.  Just add quotes.


Think of it this way.  Compared to other languages.. If you want to do 
math, do math, if you want to use a string, use a string.  I think it 
follows the convention quite nicely, other than the weird behavior of 
AEL of when you use an assignment of mixed text-math without quoting.


c
----
a = 1 + 1; /* correct */
b = "foo"; /* correct */
c = 1 + "bar"; /* syntax error */

perl
----
$a = 1 + 1;  # correct
$b = "foo";  # correct
$c = 1 + "bar"; # syntax error

php
----
$a = 1 + 1;
$b = "foo";
$c = 1 + "bar"; # treats "bar" as 0, results in a runtime warning, final 
value: $c=1

python
----
a = 1 + 1 # correct
b = "foo"  # correct
c = 1 + "bar" # runtime error


So... the only weird thing here... is AEL 'works' with "<number> 
<operand> <string>", and does something unexpected with it

Thanks for the suggestion.. I'll update the documentation and add some 
examples.
