@CharLemAznable To better convey the function's meaning, why not add a new TryCatchFinal function instead?

@CharLemAznable To better convey the function's meaning, why not add a new TryCatchFinal function instead?

@gqcn First, if a new function TryCatchFinal is added to complement the existing TryCatch function, then a corresponding TryFinal function should also be added to complement the Try function. Additionally, new methods may need to be added to gutil_groutine and g_func. In this scenario, there would be a significant amount of redundant code, increasing the burden of future modifications and maintenance.

Another reason is that the optional finally block is a common part of try-catch syntax. If added as an optional parameter to the TryCatch and Try methods, it would not impose a large cognitive burden on most users. Compared to adding optional parameters, introducing new methods represents a more significant API change.
