Certainly less so than in C++.  The term OOP comes from Smalltalk, and
the key feature is separate objects communicating through message
passing.  Objects are distinguished by having their own control flow.

Lua has yield/resume.  Ada has rendezvous.  C++ has nothing.  C++
aficionados paint member function calls/returns as message passing, but
that is nonsensical since the only way out of a function call is a
return, abandoning all control flow.

C++ has hijacked the term OOP and given it the meaning "whatever C++ can
currently do more or less".
