That's not entirely true:

my $name;

$name = 'red';
*$name = sub { "<FONT COLOR='$name'>@_</FONT>" };

$name = 'blue';
*$name = sub { "<FONT COLOR='$name'>@_</FONT>" };

$name = '<none>';

print red(), "\n";
print blue(), "\n";
__END__
<FONT COLOR='<none>'></FONT>
<FONT COLOR='<none>'></FONT>

... but when the same is done in a loop, with a lexical variable declared beforehand, the result changes:

my $name;
for $name ('red', 'blue') {
    *$name = sub { "<FONT COLOR='$name'>@_</FONT>" };
};
$name = '<none>';

print red(), "\n";
print blue(), "\n";
__END__
<FONT COLOR='red'></FONT>
<FONT COLOR='blue'></FONT>

The behaviour changes again, if you use a global:

# global $name;
for $name ('red', 'blue') {
    *$name = sub { "<FONT COLOR='$name'>@_</FONT>" };
};
$name = '<none>';

print red(), "\n";
print blue(), "\n";

__END__
<FONT COLOR='<none>'></FONT>
<FONT COLOR='<none>'></FONT>
