Hello world,

It's clear from the way that they behave that

(define %gentext-by% 
  (case ($lang$)
    <![%l10n-usen[ (("usen") %gentext-usen-by%) ]]>
    <![%l10n-dege[ (("dege") %gentext-dege-by%) ]]>
    <![%l10n-ru[ (("ru")     %gentext-ru-by%) ]]>
    (else "L10N ERROR: %gentext-by%")))

is different from

(define (%gentext-by%)
  (case ($lang$)
    <![%l10n-usen[ (("usen") %gentext-usen-by%) ]]>
    <![%l10n-dege[ (("dege") %gentext-dege-by%) ]]>
    <![%l10n-ru[ (("ru")     %gentext-ru-by%) ]]>
    (else "L10N ERROR: %gentext-by%")))

In particular (current-node) can be accessed in $lang$ if I use
the latter (literal (%gentext-by%)), but not if I use the former
(literal %gentext-by%).

Can someone satisfy my intellectual curiosity and explain the
difference?  In particular, why "current-node doesn't exist" in
the former.
