Note, this goes against the gettext documentation's recommendation:
https://www.gnu.org/software/gettext/manual/gettext.html#Contexts
> Finding a canonical msgctxt string that doesn’t change over time can be hard.
> But you shouldn’t use the file name or class name containing the pgettext
> call – because it is a common development task to rename a file or a class,
> and it shouldn’t cause translator work.
