Sorry, POSIX requires that to leave LC_ALL set after the function call,
which is not what you want (bash behaves differently according to
whether it was started as bash or sh).

$ ksh -c 'foo=bar; blah() { :; }; foo=baz blah; echo $foo'
baz
$ bash -c 'foo=bar; blah() { :; }; foo=baz blah; echo $foo'
bar
$ sh -c 'foo=bar; blah() { :; }; foo=baz blah; echo $foo'
baz
