    58 If the class body throws an exception from a literal C<...> (yada) term,
    59 the class defintion is considered incomplete, and a second definition of
    60 that class does not complain, so you can write
    58 If the class body consists only of a literal C<...> (yada) term, it is
    59 interpreted as a forward declaration that just tells the compiler that the
    60 class name is a type name, to be defined later on.

    62 class Foo {
    63 has $!some_attr;
    64
    65 ... # literal ... here interrrupts class definition
    66 }
    67
    68 # other code here
    69
    70 class Foo {
    71 # rest of class defintion here
