What is $ @ in Perl?

Question

I have a Perl script that I cannot understand.

for $i(@myarr)
{
    #some stuff
    eval {
        #some stuff
    };
    if($@)
    {
        print "*** $@ ****";
    }
}

What does this eval do? Is this a standard Perl command or just some part?
What is the variable $ @ ? He is currently printing a line, but I do not know where this line is from.
