My thanks to you for developing Euphoria!

This is the first "trap" I have found in Euphoria.

The following lines execute without any warning or error messages: 

? 0 <= 5 <= 9 
    --1 
? 0 <= -5 <= 9 
    --1

Python (and a few other languages) allow this: 

Python 2.7.3 (default, Sep 26 2012, 21:53:58)  
[GCC 4.7.2] on linux2 
Type "help", "copyright", "credits" or "license" for more information. 
>>> 0 <= 5 <= 9 
True 
>>> 0 <= -5 <= 9 
False 
>>>

The Euphoria way of writing: 

? 0 <= 5 and 5 <=9 
    -- 1 
? 0 <= -5 and 5 <= 9 
    -- 0

How do I explain what is happening?
