in reply to Foreach & scalar ref: break of way that it is suposed to work!

for $foo (...) { ... }

[download]
is more or less equivalent to 
{ local $foo; for $foo (...) { ... } }

[download]
or 
{ my $foo; for $foo (...) { ... } }

[download]
depending on what $foo is (global or lexical).

This also means that 

for my $foo (...) { ... }

[download]
is like 
{ my $foo; for $foo (...) { ... } }

You can't local or my $foo{bar}.

    The entire issue is that you can local $foo{bar}.
