Yes. I imagine something like this could create a new array called

Adding things like this to Tcl is easier than for Java or Python, but it's
more than an afternoon's work. I believe that Tcl will already wrap this
method, but the wrapped method will expect 6 values as input, instead of
expecting one name for an output array that it should create. Because the
wrappers can't really tell whether "double" is meant to be used for
input or output, the method will actually have to be wrapped twice, once
for input, and once for output. There are undoubtedly some tricky
complications that I haven't though of, however.

Because they're cool! Actually, at this point I'm fine with them going
away, but I'd still like to keep Tkinter (which works just fine without the

Any volunteers to convert TestSetGet and TestEmptyInput to python?
