If you pipe something, the recipient of the piped data will be executed in a subshell and can't set variables of the calling shell. This is just how pipe'ing works. You can do an hackish workaround like: evalfunc_stdin B test < <( echo ) to execute the function in the current shell and receive input on stdin.
