[Pdx-pm] accessing list elements

When reading through some code I came across this:
my $pic = $files[rand @files];
huh? rand returns a "random fractional number". And lists are
accessed through integers.
A simple test case shows that you can access list members with
fractional numbers. This is handy, but puzzling behavior.
I couldn't find a reference to this in the docs.
Is there any explanation to this besides "Perl does what you expect"?
