in the meantime we had a look at several script languages with a usablec api, from older ones like forth (fth), (regina) rexx, tcl, to _javascript_implementations like duktape and mujs to newer inventions likering-lang.net but so far we have not found anything that pleases us and in the long runwe will have to implement our own solution as no existing tool is up to thetask (at least we did not found one).
Well it looks to me like you are looking for perfection. When you have completed your perfect language please let us know so we can all start using it.
ALL languages are compromises and balance conflicting requirements. You are of course free to disagree with the decisions made for Lua, but that doesn't make them “crap”, it just means the Lua authors and you disagree on those compromises.
