golang.org/x/sync/errgroup — validation proof
Go’s own golang.org/x/sync/errgroup test suite, converted to C# by go2cs, built against the converted standard
library, run under the Go-semantics test host, and compared verdict for verdict against a clean
go test -json baseline of the same sources. This page is generated by the converter from that
comparison, and written beside the conversion: it is not a row of go2cs’s standard-library roster.

Excluded declarations
Declarations filtered from both sides of the comparison, and therefore not claimed above:
Benchmark, Fuzz and Example declarations the converted host does not execute, plus any
test requiring a capability the managed runtime does not provide — a testing member the host
has not implemented, or a platform behavior it provably cannot reproduce. Each is named with
the capability it needs.
- BenchmarkGo (benchmark): benchmark execution is deferred to Phase 4D
- ExampleGroup_justErrors (example): example execution is deferred to Phase 4D
- ExampleGroup_parallel (example): example execution is deferred to Phase 4D
- ExampleGroup_pipeline (example): example execution is deferred to Phase 4D
