I cannot imagine. But I cannot imagine how it were possible for which and exec, either.

    system("which $prog") would be passed through the shell. exec $prog would not be. The shell could run startup script which modify $PATH.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
      Indeed. That reminds me case of cron where $PATH may be restricted unless modified.
