The choice between static and dynamic typing is not an exclusive or.
Many times, when there are religious battles between polar opposites,
there is an opportunity for a continuum.

Perl6 will infer as much type as it can at compilation time and will
rely on dynamic typing otherwise. This means that a programmer can
start with flexibility and later commit to specific static types
when/where/if he needs speed and/or strict interfaces.  This will
complicate the implementation though.
