            Bug ID: 89823
           Summary: Composed message only partially translatable
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: goeran at uddeborg dot se
  Target Milestone: ---

In d/dmd/expressionsem.c there is this piece of code:

> const char *s = exp->op == TOKplusplus ? "increment" : "decrement";
> exp->error("cannot post-%s array slice '%s', use pre-%s instead", s, exp->e1->toChars(), s);

The string "cannot post-%s …" will be extracted for translation, but the
inserted words, "increment" and "decrement", will not.

At a minimum, these words need to be marked for translation too.  Better is
probably to make it two complete messages.  For Swedish it would work to
compose the sentence this way, but I suspect there are languages further
removed from English where it would be hard.
