IMPORTANT: [do not use eval!](https://stackoverflow.com/questions/17529220/why-should-eval-be-avoided-in-bash-and-what-should-i-use-instead) (I learned this later..)

In a function, `eval` expands `sleep` to its alias, so I prevent the endless loop this way:

```
function FUNCexecEcho() { 
  echo "EXEC: $@";
  shopt -u expand_aliases
  eval "$@";
  shopt -s expand_aliases
};
alias sleep='FUNCexecEcho sleep ';
sleep 10

```

But then, all other aliases will stop working...  

How to prevent expansion only to one arbitrary alias inside this function?

PS.: the endless loop only happens on the second time you execute `sleep 10`
