It's evaluated dynamically in the sense that you construct a different
instance at each send,
versus statically constructed at compiled time as a literal.

Note that Dolphin has syntax for statically evaluated expression at
compile time ##( 1 + 2 sin )
Of course, sin must exist, and if you later change it, you have to recompile.

And VW has the add-on caching trick:  [ 1 + 2 sin ] once,
evaluated once at first send.
A bit less problems since it doesn't depend on load order.
