My claim about the Lua C API was that, being a stack-based API, it is hard to use. It's a tradeoff between simplicity and usability from C. Please show me the code I wrote that shows how my ideas about lack of usability of the Lua C interface is due to me not reading the documentation. Note: interpreters are not entirely out of my specialization, I wrote a Tcl interpreter that is still in use in embedded systems, participated in the Tcl community for a long time, reimplemented the Joy concatenative language extending it, and so forth.
