Variable description
a quotation with stack effect ( name -- ) which loads a vocabulary. This quotation is called by require. The default value should not need to be changed; this functionality is implemented via a hook stored in a variable to break a circular dependency which would otherwise exist from vocabs to vocabs.loader to parser back to vocabs.

Variable value
Current value in global namespace:
[ dup vocab-name errorlist get at* ~quotation~ ~quotation~ if ]
