Thanks for the pointers! I don't know which way I'll go. The TYPE_CODE 
approach was the only thing I came up with, but I will look into both.

This is to avoid matching things like operator< operator<=, and 
operator<<. Come to think of it the second clause should be

strchr (c, '>') != NULL

Will do. I am not sure I understand this mechanism well, but I'll figure 
it out.
