Re: [ANN] clx 0.3.0 released

Samir, Hi!

May I ask about your perceived "strategic goal"? I.e. do you aim to create
replacement for LuaJIT (given that it drags behind the language standard)
or is it for now just a project mainly driven by developer's curiosity?

As I understand CLX doesn't provide JIT behavior, so if some code is loaded
and executed dynamically its performance should be that of typical
"interpreted" code, not matched to native / JIT execution?

thanks in advance,
sincerely yours,
Rodion
