That's not exactly a bug, it's because a parenthesized sub-expression
is valid syntax inside [[ ]]. The parser can't tell why the open
paren is there. It might be possible to special-case the operators
that accept file patterns as arguments, but right now except for "-t"
(which has special handling for ksh compatibility) the parser doesn't
use any such context dependence; that is, the operators are not
tokens, they're just one in a list of strings, a property which is
made use of by the module system for defining new condition operators.
