What method are you trying to actually bind? 

Seems like "build" method could be updated to return a LogicalResult maybe?
 Right now they look like: `void FOp::build(::mlir::OpBuilder &odsBuilder, ::mlir::OperationState &odsState, ::mlir::Value a) {`

If they were returning a LogicalResult, the current wrappers could `assert(successed(result) && "build method unexpectedly failed);`  and you could use the build methods directly for a failable use-case.
