PostInverse matches more than one declaration in GradedModules

[TKuh]

Setting

SetUserPreference( "PackagesToLoad", [ "CAP", "homalg" ] );

inside gap.ini and then executing make test inside HigherHomologicalAlgebra/BBGG yields:

testing: /home/tom/.gap/pkg/HigherHomologicalAlgebra/BBGG/tst/100_LoadPackage.tst
########> Diff in /home/tom/.gap/pkg/HigherHomologicalAlgebra/BBGG/tst/100_LoadPackage.tst:8
# Input is:
LoadPackage( "BBGG", false );
# Expected output:

# But found:

#I  method installed for PreInverse matches more than one declaration in /home/tom/.gap/pkg/homalg_project/GradedM\

@mohamed-barakat remarked, that this might point to a bug related to the order of package loading.

These errors disappear, when

SetUserPreference( "PackagesToLoad", [ "CAP", "homalg" ] );

is removed from gap.ini.

This is this issue again: homalg-project/CAP_project#586 (comment)

Minimal example:

LoadPackage( "CategoryConstructor" );
LoadPackage( "GradedModules" );

Is this relevant (=important) for you? If not, we probably won't do anything about it :D

Ah, I see.

Haha, no, it's not. :) Should I close the issue, since this is known, or shall I leave it open? (Is this even the correct place here?)

I would say we keep the issue open to make it easier to find in case someone else comes across this. And just to make sure: My rather direct question was not meant to deter you from opening such issues in the future: It's good if we are aware of such things, even if they are of minor practical relevance right now, because they might get relevant any time. So thanks for the report! :-)
