} Looks like most redirection errors are fatal, so from that point of view

Hmm.

torch% () { cat < notafile ; echo got here }
(anon): no such file or directory: notafile
got here

What was fatal about that?  Even with a builtin:

torch% () { read -E < notafile ; echo got here }
(anon): no such file or directory: notafile
got here

Even this:

torch% print =(<notafile)
zsh: no such file or directory: notafile
/tmp/zshd0zlSR

(Aside:

    cat =(<file) >| file

reads the contents into the temp file for =(...) before clobbering it
for the >| redirection.  Probably handy for something.)

Should I commit/push 33775 then?  Anybody object?
