Source[det]with_quasi_quotation_input(+Content, -Stream, :Goal)
Process the quasi-quoted Content using Stream parsed by Goal. Stream is a temporary stream with the following properties:

  • Its initial position represents the position of the start of the quoted material.
  • It is a text stream, using utf8 encoding.
  • It allows for repositioning
  • It will be closed after Goal completes.
Goal is executed as once(Goal). Goal must succeed. Failure or exceptions from Goal are interpreted as syntax errors.
