Summary: Functions do not accept variables

Initial Comment:

  <property name="MyDir" value="c:\Blah" />  
  <mkdir dir="${MyDir}" />
  
  <if test="${directory::exists('c:\blah')}">
     <!-- Executed as expected -->
  </if>

  <if test="${directory::exists('${MyDir}')}">
     <!-- The expression evaluates to false, so this
          is never executed -->
  </if>

Obviously (?) NAnt is passing the '${VAR}' literal to the function without parsing. I'm pretty sure this is not true for all functions..? I think.

I'm not sure if this is a bug or a feature, but it just cost me three hours of work =)

Simple repro attached. I'm looking at the 0.85 source to see if there's a simple cure for this that I can submit as a patch but I wanted to upload this because I couldn't find a reference to this problem in the SF.NET tracker. Maybe someone can tell me if this is a known problem.
