I certainly understand where you are coming from. There are several
Velocity features that are controllable from properties :
interpolation -> default is on
VMs -> many aspects, but default is ususally on
invalid reference warnings -> default is on
As a matter of fact, individual directives such as #macro() and
#foreach() are optional - you can actually make them stop working
through configuration. (For example, if you were insane...)
I guess the idea is that it is recognized that some these features, VMs
and interpolation for example, may be undesireable for some, and we
wanted to give them a way of just turning them off.

Agreed. The 'optionality' of interpolation wasn't for performance. I
mean, you could just not use them if you are worried about the
performance cost, right? It was really to allow a user to enforce the
decision that the interpolation feature, because if its power, is not to
be used.

Me too : I hope for a huge pile of Velocimacros. 'VMAN' or something :
Velocimacro Archive Network. :)
