2920	Putting _() into builtins causes trouble with doctests	Malcolm Tredinnick	nobody	"We install a function called {{{_()}}} as an alias for {{{gettext()}}} into {{{__builtins__}}} so that we don't have to import everywhere we want to translate strings.

The Python interactive shell uses the {{{_}}} variable to store the most recent result. Any doctests run in the same sort of environment as the interactive shell and so this variable gets nuked. If a class has doctests and uses translation functionality, chaos ensues.

One solution is to import {{{gettext()}}} and alias it to {{{_()}}} in each modules' scope. A little awkward but not inherently bad. Maybe there's another solution I haven't thought of yet, though.
