pub const UNTIL_BINDING: &str = "__poll_until";Expand description
The wire a poll’s until: expression is lowered to.
One name across node types on purpose: a phase’s poll.until and an op’s
poll.until compile to the same binding in their respective kernels, so
the reader does not care which it got. Ordinary scoping resolves it — an
op-template binding shadows the phase’s, as any other wire would.
