Because the prompt included the name of the abstract syntax, the loading of the PGF was forced even if -retain was used. Even worse, if an error occured while loading the PGF, it was repeated and caught every time the prompt was printed, creating an infite loop. The solution is to not print the name of the abstract syntax when the grammar is imported with -retain, which is the way things were before anyway.
DESCRIPTION
The Grammatical Framework (=GF) is a grammar formalism based on type theory.
It consists of
* a special-purpose programming language
* a compiler of the language
* a generic grammar processor
The compiler reads GF grammars from user-provided files, and the
generic grammar processor performs various tasks with the grammars:
* generation
* parsing
* translation
* type checking
* computation
* paraphrasing
* random generation
* syntax editing
GF particularly addresses four aspects of grammars:
* multilinguality (parallel grammars for different languages)
* semantics (semantic conditions of well-formedness, semantic
properties of expressions)
* grammar engineering (modularity, abstractions, libraries)
* embeddability in programs written in other languages (C,C++,
Haskell, Java, JavaScript)
