Libraries with a well defined API stability policy provide ad hoc versioning mechanisms at the source level, e.g., "(use-modules (gnome-2))". Likewise, applications distributed as a source package and that aim to build on a wide range of platforms are likely to explicitly check for the version of their dependencies. By saying Guile should "comply to the letter of the standard", I think Andy meant to say it should do the minimum required to be "standard-compliant". Thanks, Ludo'.
