You might also like to consider HDF5. It is targeted at large volumes of
scientific data and its capabilities are well above what you need.
MATLAB, Octave and Scilab use it as their native format. PyTables and
h2py provide Python/NumPy bindings to it.

Once you have one Qt app in a Gtk DE, or vice versa, then you have taken

Packages like reportlab with a need to support both Python 2 and 3 end
up with the worst of both worlds. The initial drive for Py3k was to drop
cruft that had accumulated over the years. Mixing old and new hampers
your ability to write clean 3 code.

This seems to me to be rather similar to sort() and sorted(). How about
giving equals() an optional parameter key, and perhaps the older cmp?
Using casefold or upper or lower would satisfy many use cases but also
allow Unicode or more locale specific normalization to be applied.
The shortcircuiting in a character based comparison holds little appeal
for me. I generally find that a string is a more useful concept than a
collection of characters.
+1 for using an affix in the name to represent a normalized version of
the input.

I beg to differ. If an expression is long or complex then splitting it
