doc/go_spec.html:3305: immediately returns the element type's <a
href="#The_zero_value">zero value</a>.
receiving is the present tense, so the immediately is implied, but of course i
know what you're trying to do.

how about

A receive operation on a closed channel always immediately....

of course, it's more subtle if there's a select involved.

maybe

A receive operation on a closed channel can always proceed immediately, yielding
the element type's zero value.
