The parser is consistent. It doesn't mark that word as a valid assignment
statement, either, which has implications for how it's expanded (for
example, it undergoes word splitting). That word doesn't contain any
metacharacters, so it's not a syntax error. It just appears as an argument
to `declare', which knows how to deal with it.
