Aha! For this reason precisely, the one producing "abcabcabc" was first 
called 'multiply' in Text. But then, I implemented it as '*' and '*='; 
seemed rather intuitive --what do you think? (various other operations 
are implemented as operator overloads) Could you do something similar 
for some algos where it makes sense (and does not feel forced)?
