NAME

C99::CPP::PAST - Abstract syntax tree nodes for C99

DESCRIPTION

This file implements the various abstract syntax tree nodes needed for C99. The currently defined ast nodes:

    C99::CPP::PAST::Node       - base class for all ast nodes

METHODS

C99::CPP::PAST::Node::unique([string fmt])

Each call to unique returns a unique number, or if a fmt parameter is given it returns a unique string beginning with fmt. (This may eventually be generalized to allow uniqueness anywhere in the string.) The function starts counting at 10 (so that the values 0..9 can be considered "safe").
