4 * Tests for the token lsym_rbrace, which represents a '}' in these contexts:
5 *
6 * In an initializer, '}' ends an inner group of initializers, usually to
7 * initialize a nested struct, union or array.
8 *
9 * In a function body, '}' ends a block.
10 *
11 * In an expression like '(type){...}', '}' ends a compound literal, which is
12 * typically used in an assignment to a struct or array.
13 *
14 * In macro arguments, a '}' is an ordinary character, it does not need to be
15 * balanced.  This is in contrast to '(' and ')', which must be balanced.
16 *
17 * TODO: try to split this token into lsym_rbrace_block and lsym_rbrace_init.
18 *
19 * See also:
20 *	lsym_lbrace.c
