Then I would have chosen Ada without a moments hesitation. I fell in
love with that language right away, and I believe that Ada compilers and
C++ compilers are equally complicated. It's a pity that Ada did not gain
the popularity of C++ but that is probably due to the fact that Ada came
too late (I know that C++ emerged later than Ada, but by that time
probably too many people were using C already, and the transition from C
to C++ is more "natural" than the transition from C to Ada, I guess).

When I started programming with C++ I did not want to learn too much,
especially not that nifty template stuff. My coding style in those days
can best be described as "C-ish": I wrote the usual procedural code, but
instead of messing around with char* pointers and strcpy, I used
std::string (I only realized much later that this is already a templated
class).
Later I started to write my own classes and was thrilled. OOP! My man,
this rocked.
On day I stumbled upon a loop that ran really slow: It iterated over the
pixels of an image. Since my image could be either 8bits or 16bits so I
had to provide a virtual getPixel method. This was particularly clumsy:
My algorithm had to invoke a virtual method million of times only to
discover that it actually invoked the _same_ method each time. It would
be much better if I could have two versions of the same algorithm for
two different data types, thus avoiding the million virtual method
invokations.
It turned out that all I had to do was to make it a template function.
Easy, peasy, japanesey.
That's how it all started with this template stuff. Ten years later I
was writing code like this
template<class t_BaseImpl, class t_CoClass = t_BaseImpl::CoClassType>
class HAirCushionSwitchHelper : public t_BaseImpl
{
...
even before I had my morning coffee.
Admittedly, I have not had the guts to delve deeper into template
metaprogramming, but one should never say never. That's what I like
about C++: There is always a new continent to discover, but only when
you need it.

Stuart
