Interpreter: Amend parameter naming
Drops prefixed underscores from parameters The C++14 standard states in section 2.10 subsection 3.2: "Each identifier that begins with an underscore is reserved to the implementation for use as a name in the global namespace." It's highly unlikely an implementation will ever use '_inst' as a global identifier, however it's better to just amend the names and alleviate the concern altogether.
