Re: c++: too many templates?

[John Fine <johnsfine at verizon dot net>]

In your real code, did you do something to make f public so test can use 
it?  But that isn't the main problem.  Arturs Zoldners gave the solution 
to the main problem:

If I understand correctly, while processing the definition of test, the 
compiler doesn't look at the definition of C, so it doesn't know f is a 
templated function, so it doesn't know how to parse the "<" in "c.f<int>".

When it instantiates test<T> it will, of course, look inside C<T> (for 
at least the constructor of C and the declaration of f).  But if it 
can't process test at definition time, it never gets to instantiation.
