🙋 feature request

Utility function that raises an exception when an operation has failed.

🤔 Expected Behavior

tc.operation.check(op_fail) # raises exception

😯 Current Behavior

Have to implement a check function in every repo in userland.

💁 Possible Solution

def check(op: tc.Operation):
    if not tc.operation.succeeded(op):
        raise RuntimeError("Operation failed.")
    return op
