I literally have an example of this:

There's a few different ways we could do it, this here is working 
with the existing D gettext lib which married itself to 
std.format (much to my chagrin) but it still wasn't hard to make 
it work.

Remember, the library can tell the difference between the string 
literal segments and the interpolated segments, and it can work 
with the string literal segments at compile time. So it can CTFE 
msgids out of it in whatever format it wants and list all the 
possible things for the .pot file through compile time reflection 
(aggregated at runtime).

These are all solved problems - my thing is a small wrapper 
around the existing gettext D lib which is a small wrapper around 
GNU gettext. All you have to do is arrange the data available to 
you.

In my example, I used $1, $2, etc as placeholders for the 
parameters in the msgid/msgstrs, except for the plural param 
which had to be %d cuz the D gettext lib made that assumption and 
im trying to be compatible with it. This allows easy reordering 
etc by the translator, without conflicting with std.format's %s 
stuff.

Look at that repo to see for yourself.
