> There are some known issues that need to be fixed. For example it seems that
> arity of a function is not checked when calling it, and same is true for
> parameter types. Calling an undefined function is evaluated to null and
> sometimes it seems that incorrect syntax is silently ignored.
> In cases like this a helpful error message would be expected, thought we
> should also consider how PL/SQL works and maintain compatibility.
