Indeed, you're quite right. I did meant to mention channels, honest, but
forgot. CSP concurrency is one of Go's nicer features.

...according to Wikipedia CSP was first described in a paper in 1978;
Occam came out in 1983 (although it looks way older from the syntax).
Perhaps Algol-68 simply predates it, which would explain why it has par
but no channels. Anyone modernising the language would definitely need
to add them.
