the classic case which is used in the constant pragma is:
sub FOO() { 'foo' }
the last (and only) expression is returned. the () make it a prototype
with no args so it will reduce to the constant value at compile time.
it is mostly when you see stuff like this:
sub foo {
# code here
$stuff ;
}
$stuff is returned if it falls through to the that line. simple.
as i said don't do that unless it is a special case. use explicit return
statements.
