Code Review

This pull request renames the test function TestTestgop to TestTestxgo and adds a disabled test _TestTestgo in cl/compile_testdir_test.go. It also introduces a new test file cl/_testgo/types/in.xgo. Feedback was provided regarding an unexported function call cmplx.sqrt in the new test file, which should be capitalized to cmplx.Sqrt to avoid compilation errors.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

The bulk rename (_testgop → _testxgo) and test-function updates are clean. Note: cmplx.sqrt in the new fixture is valid XGo — the language supports lowercase-first-letter calls to exported Go identifiers (same pattern as os.open, re.matchString in _testxgo), so that is not a bug.

Findings

CLAUDE.md:40 and CLAUDE.md:126 — stale directory references (not updated in this PR)

Two lines in CLAUDE.md still reference the old path cl/_testgop/ which no longer exists after this rename:

• Line 40: "Testing: Add comprehensive test cases in cl/_testgop/ covering various usage scenarios"
• Line 126: "Phase 2: Comprehensive test coverage for semantic implementation in cl/_testgop/ covering:"

Both should be updated to cl/_testxgo/.
