Chez Scheme, which is one of the few Schemes to currently have native
threading, provides thread local parameters for controlling the level of
sharing data accross threads. Combined with regular parameters, this makes
life much easier. Programming for concurrency is still harder than it has
to be, but all the basics are available.
