Well I learned something. But if you represent a list as a lift of strings wouldn’t it have to parse them as Argv in the c implementation? It has been a while but only 17 years since I wrote TCL commands but each one started with a list of strings. Maybe the byte code interpreter doesn’t work with older C extensions? But the main selling point of TCL was easy extension.

Only if you were using the pre-Tcl 8 FFI API, our startup was built on a Tcl "Rails" similar to AOL Server, and we did plenty of native bindings.
