New feature in v3: cast!

[Alan DeKok]

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

  if (<ipaddr>127.0.0.1 < &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 > 127.0.0.1) {
	...
  }

  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
variable.

  This is another minor feature which just makes things nicer.
