It would be helpful to have a syntax for pointer type casting,
for times when the static type of the pointer does not match
the dynamic (actual) type.  Currently, this requires embedded-C
code to get around.

Perhaps like this:
    $ptr("struct tcp_socket")->tcp_socket_field

A more C-like syntax would be:
 ((struct tcp_socket*)$ptr)->tcp_socket_field
but parsing that is much more complicated.
