Everybody here knows you can bind to C++ instead of C. What they're saying is, if you have Lua or Python, C is virtually certain to be enough; the higher-level architecture/object graph stuff is better dealt with in Python anyways.
This claim sure doesn't jive to me. I got a simulation that does millions of GIS calculations involving entity tracks and regions. Moving the object graph into Perl or Python would take six hour runtimes into weeks. And writing it in C would be sheer torture.
Perhaps, but I don't think the situation would be as awful as you suggest.
It is possible to write significant revenue-producing commercial software using Lua for control logic calling compiled modules, and expect it to perform every bit as fast as a similar app written 100% in a compiled language.
