I'm trying to do something like:

 List<Cmd<T>> queue;

where List and Cmd are both templates, ListItem is helper
template for List, and T is typically a function pointer.
This got a compiler error.

The alternatives seems to be:

 1) make a class with two lists:
  List<Cmd> cmdQ;
  List<T> funcQ;

 2) subclass T under Cmd

I don't like either solution.  Anyone got better ideas?

Please send email to me directly at chiu@stdavids.picker.com

Thanks,

Arnold.

What's the compiler error?  If you programmed it exactly as shown above, the
error is probably because the "maximum munch" rule forces the compiler to
parse >> as a single token.  Try adding a blank between them:

        List< Cmd<T> > queue;

This is a Frequently Asked Question and the problem is mentioned
in the FAQ list for comp.lang.c++.
Use the following instead:
 List<Cmd<T> > queue; // note the extra space !

Try putting a space between the two right angle brackets:
List <Cmd<T> > queue;

Then figure out how your compiler was parsing your first expression,
and you will see why it was giving you an error.
