Correction: it doesn't really get the value from _s attribute:

 >>> astr = lstr('abcdef')
 >>> astr.s
 >>> astr.s='xyzzy'
 >>> astr
 >>> astr.s

So my updated question is where does this lstr() instance keep the 
original value ('abcdef')? It obviously has smth to do with inheriting 
after str class, but I don't get the details of the mechanism.
