4 * Tests for the token lsym_period, which represents '.' in these contexts:
5 *
6 * In an initializer, '.' starts a named designator (since C99).
7 *
8 * In an expression, 'sou.member' accesses the member 'member' in the struct
9 * or union 'sou'.
10 *
11 * In a function prototype declaration, the sequence '.' '.' '.' marks the
12 * start of a variable number of arguments.  It would have been more intuitive
13 * to model them as a single token, but it doesn't make any difference for
14 * formatting the code.
15 *
16 * See also:
17 *	lsym_word.c		for '.' inside numeric constants
