# --------------------------------------------------------------
#
# INTERNAL PARSING UTILITIES
#
# The use of com_node() introduces a lot of extra stack frames,
# enough to cause a stack overflow compiling test.test_parser with
# the standard interpreter recursionlimit. The com_node() is a
# convenience function that hides the dispatch details, but comes
# at a very high cost. It is more efficient to dispatch directly
# in the callers. In these cases, use lookup_node() and call the
# dispatched node directly.
