It just occurred to me that in gettext, "key" *is* the English string... So all 
gettext really does is create a POT with the key, the PO is created with the 
localized string, and the binary MO provides the localized string if present 
and if not the program displays the original which already is *in* the code...

The key=string format I'm showing above is actually the format Java programs 
use (and until now I was mostly involved with i18n/l10n of FOSS java programs). 
So the programer is actually creating the catalogue leaving only arbitrary key 
names in the source...

Is it very different from global variables clashing or not between packages?

Yes, but to me it looks like gettext works like it does this because C is not 
an interpreted language and forcing Lisp code to use the full gettext process 
does look a bit unnatural.

I can see that we use gettext to extract strings and create POTs to get POs. 
But once the POs are there, do we need to create binary MO blobs ? I'm not sure 
at all. So in the end gettext would be used only for string extraction and a 
few checks. But I may be missing something important here...
