Importance: Low

Hi,
 
I am looking for a way to access the value of an Object put in the
Velocity context using a String containing its name:
 
#set ( $foo = "some value" )
#set ( $bar = "foo" )
 
How can I use $bar to display "some value"
 
I tried things like:
 
$$bar
$"$bar"
 
and so on... without success.
 
The idea is to have a macro where both the name of a parameter and its
value can be outputted:
 
#macro ( m $paramName )
  <input type=text name="$paramName" value="???">
#end
 
using:
   #m ("foo")
 
would result in:
  <input type=text name="foo" value="some value">
 
Thanks for any help.
