[Pdx-pm] accessing list elements

[Michael Rasmussen]

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.  

Or not?

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"?
