The statically scoped method is usually best. But another technique involving tied variables and local scoping is explored here: Abigail shows how to tie a variable to the cwd, then use 
tie $cwd => 'main';       # the example ties in package main
{
  local $cwd = '/some/other/directory';
  # execute in /some/other/directory
}
# resume in original working directory

This technique will obviously work for other ties too; it is probably more appropriate when initialisation and finalisations are such paired opposites.
