Not exactly.
While it is better (and I mean really, really better) to use the functional glob, you still can force perl to interpolate variables. Actually, only filehandles and simple scalars are not interpolated (see perlop). So these: are interpreted as globs. Note that this is a caveat in the last case! Since you probably want the <> to do a readline in the last case, people really need to be aware that nested structures are always globbed. Only simple, straightforward variables like $foo result in readlines.
