This will print `no_such_file` if such file exists and will do nothing
otherwise.

Not precisely nothing ... it will print a newline.

If the file doesn't exist, the command is equivalent to this:

print -rC1 --

This command doesn't print anything.

% print -rC1 -- no_such_file(N)

zsh 5.8 (Ubuntu): prints nothing

zsh 5.7.1 (Mac): prints return
