A statement (in perl) is anything that is ended with a ";" while an expression is the part of a statement that actually does something like a mathematical computation, or the assigning of a value etc.

So, in

for (my $i = 0; $i < 10; $i++) {
    print "\$i = ";
    print $i
}

there are three statements, my $i = 0;, $i < 10; and print "\$i = ";, but print $i isn't, and neither is the entire for construct?

Curious.
