uops I got a nose punc for this :-)

>a=1
>while a=1 or (T >=25)
>    a=0
>    R=Themistor.ReadResistance()
>    T=R_to_Temperature(R)

First of all, this doesn't produce the exact same behavior unless python
uses lazy evaluation (does it?)
Two this is ofcourse not the ONLY way to acive the behavior.
Björn Peterssen said another one in the first message.
I have just benn tought to not use goto and I counted break as a nobler art
of goto :-)
