New feature in v3: cast!

  Not fishing casts, but data type casts. :)  See "man unlang" for details.

  if (<ipaddr> < &Framed-IP-Address) {

  It allows you to do type-specific comparisons.  v2 usually did string
comparisons for conditions.  To get type-specific comparisons, you
sometimes needed to put the data into an intermediate variable.

  That was ugly.  The casting is nicer.

  That being said, the above example *did* work in v2, with some changes:

  if (Framed-IP-Address > {

  That worked by parsing the RHS into a temporary variable, and then
doing type-specific comparisons.  But you couldn't do:

  if (<date>"January 1 2014" < "%{sql: SELECT ...}") {

  You had to put one or the other of the strings into an intermediate

  This is another minor feature which just makes things nicer.
