Old IFS value can be preserved by using `local' keyword or (...) braces, too.
It's a bit better than polluting global scope with temporary variable.

  $ echo -n "$IFS" | (vis -w; echo)
  \040\^I\^J

  $ for i in $(find . -type f); do echo $i; done
  ./My
  Long
  File
  Name
  ./Another
  File

  $ f() { local IFS=; eval "$@"; }
  $ f 'for i in $(find . -type f); do echo $i; done'
  ./My Long File Name
  ./Another File

  $ (IFS=; for i in $(find . -type f); do echo $i; done)
  ./My Long File Name
  ./Another File

  $ echo -n "$IFS" | (vis -w; echo)
  \040\^I\^J
