Career reasons?  I believe Stepanov is on record as stating that at
least part of the reason for using C++ is that the STL can be programmed
more efficiently in that language than in Ada.  I *think* he was talking
about Ada 83.  And I think he was mainly referring to the ability to
make pointers into the middle of an array, and to do address arithmetic
on them.  The former is easy in Ada 95, and the latter is possible,
although it requires jumping through some hoops.
