Sounds like a fine idea.

While you're in there, do you want to do something about supporting NULL
inputs and results properly? Right now, a NULL input comes into a pltcl
function as an empty string, which is OK as far as it goes but you can't
always tell that from a valid data value. There should be an inquiry
function to tell whether argument N is-null or not. Also, AFAICT
there's no way for a pltcl function to return a NULL. The most natural
Tcl syntax for this would be something like
return -code null
but I'm not sure how hard it is to persuade the Tcl interpreter to
accept a new "-code" keyword without actually changing the Tcl core.
Worst-case, we could invent a new statement "return_null" ...
