TODO list

0. Add a C++ class iterator version for A(...), etc in Q.h. For example:

	I(A(x,symbol_table,length(x) > 10))

1. Add a include file for assert.h compatibility; this would be nice
   but might be a bastard to install automatically since it would wipe
   out the old one.

2. The check target requires everything to be installed to run 
   since it calls shell programs with absolute pathnames. 

3. Modify the nana scripts to call g++ if thats appropriate
   rather than gcc.
