Well, introducing a new library would create compatibility issues that
we'd just as soon not deal with, so I think that that's only likely
to be seriously entertained if we decide that Spencer's code is
unmaintainable. That's not a foregone conclusion; IMO the only fact
in evidence is that the Tcl community isn't getting it done.
Since Brendan Jurd has volunteered to try to split that code out into a
standalone library, I think such a decision really has to wait until we
see if (a) he's successful and (b) the result attracts some kind of
community around it. So in short, let's give him a couple years and
then if things are no better we'll revisit this issue.
regards, tom lane
