/*
 * Tests for the token lsym_lbrace, which represents a '{' in these contexts:
 *
 * In an initializer, '{' starts an inner group of initializers, usually to
 * initialize a nested struct, union or array.
 *
 * In a function body, '{' starts a block.
 *
 * In an expression, '(type){' starts a compound literal that is typically
 * used in an assignment to a struct or array.
 *
 * In macro arguments, a '{' is an ordinary character, it does not need to be
 * balanced.  This is in contrast to '(', which must be balanced with ')'.
 *
 * TODO: try to split this token into lsym_lbrace_block and lsym_lbrace_init.
