[erlang-questions] Execute module code from stored anonymous function

[Dmytro Lytovchenko]

In your case the pointer to function is stored internally and it goes
extinct when module is gone.
If you make it calculate function at runtime by, say, calling
apply(mprocess, process_template, [test]), then it should work.
