How to tell the compiler to distinguish between package name and method name in PL/SQL code

[Claus Pedersen]

Note: this is not a question related to PLD, but to the PL/SQL compiler in general. I was thinking since we have some many experienced developers in here, I might get a qualified answer.
So sorry in advance, if this will be regarded as spam.

Here goes:

I have a package PAY with method MY_BILL.

In the same schema, I also have a package MY_BILL with a method named MUST_BE_PAYED (so both a package and a packaged method with the same name, in same schema).

My problem is that I can not call method MY_BILL.MUST_BE_PAYED from within package PAY, as the compiler gives error: PLS-00302: component 'MUST_BE_PAYED' must be declared
The compiler wrongly assumes that MY_BILL is a reference to the method PAY.MY_BILL and not the package method MY_BILL.MUST_BE_PAYED

I know I can force references to e.g. a method variable by prefixing the variable with the method name, but how can I force the compiler to interpret a name as a package name (other than giving either the package or the method different names)? I do not want to prefix the package name with schema name, as our code must be transferable between schemas without changes in code

If you fully qualify the procedure it will work, so .. or demo.mybill.mustbepayed.
