Will Glass-Husain resolved VELOCITY-50.
---------------------------------------

    Resolution: Won't Fix

This is expected behavior for Velocity at this point.  #if can be used to detect \
boolean values or to detect existence of a reference.

> RFE: invalid parameters for #if directive should be a parse error?
