I read your example, and wondered how this would interpolate:

my $R="foo";
print "${R}[0]\n";

I thought it would either interpolate $R and print foo[0], or interpolate as $R[0], and print an empty string. Instead, I got an unexpected result:

[0]

Anyone know why? I have a feeling I might be missing something in the meaning of ${R}[0].

These act in the expected way:

my $R = "foo";
my $R[0] = "bar";
print "${R}\[0]\n";
print "${R[0]}\n";

Any enlightenment?

Update: Ah, that makes sense, a bit too subtle for me to get without some help. Thanks!
