Constructors with arguments snake-cased version

[jhonabreul]

Fixes:

• Calling constructors with snake-cased named arguments.
• PyObject arrays precedence over base class array arguments:
  • If the array item type of a different method overload argument is a base class of the PyObject instances class, that method could be matched over the one getting the PyObject array because both arguments had the same calculated precedence.
