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
