In Qt, signals and methods are member functions in a C++ class, so they
can only exist at the same time if they are overloads of one another
However, overloads of same name are considered not portable on D-Bus, so,
no, you're not allowed to use the same name for both signals and methods

"delete" is also a reserved word in C++. An interface with such a name
will fail to compile.
