Here is an example of code generated by tablegen that will cause a compiler error if the `parseX()` function returns `LogicalResult`:
```
    auto odsResult = parseInferredArrayType(parser, elementsTypes, elementsOperands, resultRawTypes[0]);
    if (odsResult) return ::mlir::failure();
```
See also `parsePrettyLLVMType()` in LLVMTypes.h, `parseSingleBlockRegion()` in IRDL.cpp, `parseDynamicIndexList()` in ViewLikeInterface.cpp, etc.
