Unexpected string behaviour: txt = 'this' ' works'

I did a double take when debugging an error the other day. My
problem was missing out a comma when building a list of strings.

Much to my surprise the offending code still executed to cause
problems later on:

txt = 'this', 'works'
print txt
('this', 'works')
# As expected
txt = 'this' 'works'
print txt
thisworks
# Eh?

I have never seen this behaviour before, but it works in Python 2.2.1
and 2.5.4 so I guess it's meant to be there. I assume it is a feature
of the compiler.

Any thoughts?

Chris
