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".
