} I feel like there is a difference between "this is a valid glob that
} has no matches" and "this is a syntax error", and this is that
} difference.

If that were it then nobadpattern should fix it, yet for qualifiers it
still fails.

% setopt nonomatch nobadpattern
% echo x(z)
zsh: unknown file attribute: z
% 

But on the other hand:

% unsetopt nobadpattern
% echo x(,)
x(,)
% 

} % echo a(
} >
} 
} also doesn't "work".

Close the paren and you get

zsh: unknown file attribute: \n

I can counter-example that one, too:

% echo x(:
> )
x(:
)
% 

A missing numeric argument is an error, but an invalid colon-modifier
is not?

(I'm not really arguing that we should change anything, unless somebody
is convinced by this discussion that I should be.)
