async.Forextension method enablesforloops overAsyncSeq<'T>within async computations, but had no test coverageActions Taken
AsyncSeqExtensions Tests (3 tests):
async.For with AsyncSeq should work- Tests basic iteration over AsyncSeq within async computation expressionsasync.For with empty AsyncSeq should work- Tests edge case with empty sequencesasync.For with exception in AsyncSeq should propagate- Tests exception propagation through async.For loopsThese tests cover the core functionality of the AsyncSeqExtensions module, specifically the extension method that allows
forloops over AsyncSeq within async computation expressions.Changes in Test Coverage Achieved

Other Areas for Future Improvement
Based on current coverage analysis, remaining improvement opportunities:
AsyncSeqOp<T>: 33.3% coverage (though PR Daily Test Coverage Improver: Coverage Analysis and Dead Code Investigation #183 identified this as containing dead code)Utilsmodule: 79.6% coverage (though PR Daily Test Coverage Improver: Coverage Analysis and Dead Code Investigation #183 identified unused code)AsyncSeqmodule: Still has opportunities for edge case coverageCommands to validate coverage numbers
