|Problems? Is your data what you think it is?|
Ok, then how will this work: $class = MyModule::MySubModule;
The obvious answer to that question is: It won't work.
This is giving error for wrong syntax.
Unsurprising. If your code isn't syntactically correct, you will get an error.
Is there a subroutine called MySubModule in the package MyModule?
If not, what do think $class will end up containing?
The lesson here is that if you make stuff up when asking a question, instead of showing the actual problem code; the answers you get probably won't work for your actual code. So stop being ... and ask the real question you want answered!

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
