}   [[ -z 'foo.<28->.jpg(N[2])' ]]
} which is no use.

It's not eval that quotes that, it's [[ ]].  The argument to -z et al.
is never expanded as a glob pattern.

If you use [ -z ... ] instead, you'll get better results.  Well, except
in 4.0.6, where you'll get a core dump, but that seems to be fixed in
4.0.7 and 4.1.1.

So without the function, it's

print -l *.??.jpg(e@'eval "[ -z ${~REPLY:r:r}.<${~REPLY:r:e}->.jpg(N[2]) ]"'@)

where @ is chosen as a character that appears nowhere in the expression.
