The '?' signifies an optional argument, but it's used in the C API only. Tcl already has defaults, which is effectively an optional argument. Having the programmer explicitly handle optional args when using the C API is faster and more natural, I think. All that's surfaced in the Tcl API so far is options and the end of options marker. Args, defaults and the 'args' list is also implemented, but of course that's standard Tcl behaviour. Where we left the discussion last time is how to deal with type checking. Boolean switches and range values are basically just forms of type checking. Depending on how type checking is implemented, then the syntax of an arg specification may change. You may or may not end up pulling your hair out later if you change all your code to use ns_proc now... :-)
