Why were you thinking of this, and why is it important enough to
override “explicit is better than implicit”?

The name ‘_’ already sees a lot of use as an identifier. It is in common
use as a conventional shortcut to the ‘gettext.gettext’ function. It is
also commonly used as a name to bind to a value that is returned from
some process but not actually needed.
Overloading existing conventions of that valid identifier with this
special construct is too much, in my view.

I disagree; it is too easy to miss.
