How to find package functions that are shadowed?

I'm missing something.
It is possible to have several package functions with identical fully qualified names, e.g. p1.test, on the search path. The statement
which( 'p1.test', '-all' )
should be the way to discover shadowed package functions. However, I fail to make that work. This script below illustrates my problem. which() finds only one of the two p1.test
%%
addpath( cd )
mkdir( cd, '+p1' );
mkdir( fullfile(cd,'f1'), '+p1' );
addpath(fullfile('.','f1'));
str2txt( fullfile(cd,'+p1','test.m'), '% test' );
str2txt( fullfile(cd,'f1','+p1','test.m'), '% test' );
%%
cd ..
which( 'p1.test', '-all' )
/users/mss.system.iBN0QN/f1/+p1/test.m % static method or package function
%%
function str2txt( ffs, str )
fid = fopen( ffs, 'wt' );
fprintf( fid, '%s', str );
fclose( fid );
end

Hi per,
This is one of the limitations of the “which” function and as of MATLAB R2024a, using the syntax:
which(some.package.fcnName, -all)
This would only give the first path for the package function “fcnName” it finds.
There is a workaround though that you can use instead; which works in both MATLAB R2024a and R2018b:
which -all +some/+package/fcnName
The above will get you all the path of “some.package.fcnName” present on MATLAB’s path.
Hope it helps.
