> In any case, is this urgent at all? I think it makes more sense to do
this as part of the upgrade to PARI-2.6, because PARI-2.6 does change the
error handling mechanism quite a bit.
The current implementation has its problems (see the ticket description),
but I know of nothing that is broken in practice. Whether to do it now or
during the upgrade depends on which solution is chosen.
- Option 1: use the try/catch macros provided by PARI. This we can do
now, and it will make the upgrade easier, since similar macros are
provided in 2.6 (albeit with slightly different names and a different
implementation).
- Option 2: keep using undocumented PARI functions/variables. This can
only be done at the same time as the upgrade, since the internals have
changed a lot in 2.6.
Option 1 is what the current patch does, and I still prefer this option.
