I think that if you are worrying about the overhead of the tkinter
bindings for Python, you're guilty of premature optimization. The tkinter
package in Python 3.3 is trivially small, under 2 MB.
Besides, how far do we go? Do we expect people to install (say):
python3-copy
so that those who don't need the copy module don't have to install it?
sudo apt-get python3 python3-copy python3-dis python3-doctest \
python3-csv python3-logging python3-shutil ...
There are advantages to having the *standard library* actually be, you
know, *standard*.
In my perfect world, the tk/tcl bindings and the tkinter package would be
installed with any Python installation. Naturally they won't work if you
don't install Tcl, but to make them work, all you need is:
sudo apt-get python3 tcl
Don't want Tcl? Fine, don't install it, and "import tkinter" will fail at
import time, preferably with a sensible error message like "Tcl not
installed".
Naturally I'm just talking about the standard CPython implementation on
Linux systems where Tcl is standard. If you have an embedded system,
where tkinter's 2MB is *not* trivially small, or a platform where Tcl
does not exist, then that's a different story. But in a standard Linux
desktop install of Python, tkinter should Just Work once you install Tcl.
In my perfect world.
