Right, I placed a smile there. Any bugfix bears new bugs in it. The problem
is of course in the relation between new and old bugs.

Of course not. My point was simple, a wider use gives a better product. The
bugs I saw in GNAT would be detected earlier if more software were written
in Ada and compiled with GNAT, just a statistical observation.
