I already made some changes, the symbolsets are now singletons, as
Other things that come to mind:

My preference would be to make the initWithString:usingSymbolSet: the
designated initializer. This is probably the most common case. When
using an array of symbols, the symbolset is already known from the
original sequence, so that one can be used. If no symbolset is used,
the code in sequencetypefromstring can be used to determine what the
symbolset should be.
* do we still need the 'skippingunknownsymbols' flag?
I would say no. I cannot think of a situation when that flag will be
NO. And also using a symbolset will filter these out.
