That would certainly be useful to avoid sys._getframe() calls in my library,
although I'd probably want the third argument to be optional (I wouldn't use
it).
If '{foo}' or '${foo}' syntax is adopted (with no allowance for '$foo'), it's
very unlikely I'd use that over string.Template for internationalization, but
the above would still be useful.
