I don't know about anyone else, but I would think that:

  display( name );

would /not/ change the variable name.  OTOH:

  display( out( name ) );

is much more clear.

To assuade those that still think there may be ambiguity, what about
'in'?

  display( in( name ) );

If you see parameters with no qualifiers, it's ambiguous, otherwise,
it's extremely clear.
