for macht mehr als das while.

ein aspekt aus camel seite 100:
"if LIST is an actual array ..., you can modify each element of the
array by modifying VAR inside the loop."

oder, perldoc perlsyn:
"If any element of LIST is an lvalue, you can modify it by modifying
VAR inside the loop. That's because the foreach loop index variable is an implicit
alias for each item in the list
that you're looping over."
