I'm getting an error from even the simplest definition that has a named
parameter. Test program:

@SysInclude { doc }

def @Blah
  left x
  right y
  named @Hiya {}
{y}

@Doc @Text @Begin
@End @Text

Giving me an error 6,3: fatal error: opening left brace or @Begin of @Blah
expected.

What am I doing wrong this time?
