No. The one thing that's QUITE clear is that there are multiple ways
to do this, some of which are more readable than others, but there's
no "one obvious way".

Hmm... I doubt it. I'd expect the translate() version to be the
fastest, with multiple string.remove()'s being competative when
the number of different characters to be removed is small. RE's
are NOT renown for their speed when doing simple character
replacement, deletion or insertion on strings. But _I_ haven't 
timed it either, so I'm going to shut up now.
