SYNOPSIS
	mixed get_type_info(mixed arg, int flag)

DESCRIPTION
	Returns info about the type of arg, as controlled by the flag.

	If the optional argument flag is not a number, an array is
	returned, whose first element is an integer denoting the data
	type, as defined in <lpctypes.h>. The second entry can contain
	additional information about arg.
	If flag is the number 0, only the first element of that array
	(i.e. the data type) is returned (as int). If flag is 1, the
	second element is returned. If flag is neither 0 nor 1, -1 is
	returned.

	For mappings, the second entry is the width (i.e. number of
	data items per key).

	For closures, symbols and quoted arrays a parser-internal
	number is returned as additional info about arg, maybe good
	for debugging the lpc machine.

	For all other data types, -1 is returned as additional info.

BUGS
	This function seems to be due to frequent changes as the
	driver develops resp. is debugged.
