the future, that same effort can introduce synchronization primitives
to meet that need.

CSP Library
-----------

A ``csp`` module would not be a large step away from the functionality
provided by this PEP. However, adding such a module is outside the
minimalist goals of this proposal.

Syntactic Support
-----------------

The ``Go`` language provides a concurrency model based on CSP, so
it's similar to the concurrency model that subinterpreters support.
``Go`` provides syntactic support, as well several builtin concurrency
primitives, to make concurrency a first-class feature. Conceivably,
similar syntactic (and builtin) support could be added to Python using
subinterpreters. However, that is *way* outside the scope of this PEP!
